HMC1010LP4E
General Description
Features
Functional Diagram
The HMC1010LP4E Power Detector is designed for
RF power measurement, and control applications
for frequencies up to 3.9 GHz. The detector provides
an accurate RMS representation of any RF/IF input
signal. The output is a temperature compensated
monotonic, representation of real signal power, mea-
sured with an input sensing range of 60 dB.
The HMC1010LP4E is ideally suited to those wide
bandwidth, wide dynamic range applications, requir-
ing repeatable measurement of real signal power,
especially where RF/IF wave shape and/or crest factor
change with time.
The integration bandwidth of the HMC1010LP4E is
digitally programmable with the use of input pins SCI1-
4 with a range of more than 4 decades. This allows
the user to dynamically set the operation bandwidth
providing the capability of handling different types of
modulations on the same platform.
The HMC1010LP4E features an internal OP-AMP at
output stage, which provides for slope & intercept ad-
justments and enables controller application.

POWER DETECTORS - SMT

11 - 16
Monolithic true-RMS detectors are in-effect analog calculators, calculating the RMS value of the input signal, unlike
other types of power detectors which are designed to respond to the RF signal envelope. At the core of an RMS
detector is a full-wave rectier, log/antilog circuit, and an integrator. The RMS output signal is directly proportional
to the logarithm of the time-average of VIN2. The bias block also contains temperature compensation circuits which
stabilize output accuracy over the entire operating temperature range. The DC offset cancellation circuit actively
cancels internal offsets so that even very small input signals can be measured accurately.
Conguration For The Typical Application
The RF input can be connected in differential conguration, or single-ended conguration: see “RF Input Interface”
section for details on input conguration.
The RMS output signal is typically connected to VSET, through a resistive network providing a Pin -> RMSOUT
transfer characteristic slope of 36.6mV/dBm ( at 900 MHz), however the RMS output can be re-scaled to “magnify”
a specic portion of the input sensing range, and to fully utilize the dynamic range of the RMS output. Refer to the
section under the “log-slope and intercept” heading for details.
Due to part-to-part variations in log-slope and log-intercept, a system-level calibration is recommended to satisfy
absolute accuracy requirements: refer to the “System Calibration” section for more details.

RF Input Interface
The IN+ and IN- pins are differential RF inputs, which can be externally congured with differential or single-ended
input. Power match components are placed at these input terminals, along with DC blocking capacitors. The coupling
capacitor values also set the lower spectral boundary of the input signal bandwidth.
Differential (Diff) Input Interface:
The value of R1 depends on the balun used; if the
balun is 50 on both sides of the SE-Diff conversion,
then
R1 = (150 * RM)/ (150 - RM) Ω, where
RM = the desired power match impedance in ohms
For RM = 50, R1 = 75 ≈ 68
Single-Ended (SE) Input Interface:
Tuned SE-interface for signal frequency = 900 MHz
Use R4 = 27, R11 = 82, C3 = 100 pF, L1=6.8nH, C4=5.6pF, R10 = 0. Refer to application circuit for single-ended

RMS Output Interface and Transient Response
The HMC1010LP4 features digital input pins (SCI1-SCI4) that control the internal integration time constant. Output
transient response is determined by the digital integration controls, and output load conditions.
Shortest integration time is for SCI=0000, allowed longest integration time is for SCI=1100 (1101, 1110 and 1111 SCI
settings are forbidden states).
Using larger values of SCI will narrow the operating bandwidth of the integrator, resulting in a longer averaging time-
interval and a more ltered output signal; however it will also slow the power detector’s transient response. A larger
SCI value favors output accuracy over speed. For the fastest possible transient settling times set SCI to 0000. This
conguration will operate the integrator at its widest possible bandwidth, resulting in short averaging time-interval
and an output signal with little ltering. Most applications will choose a SCI setting that maintains balance between
speed and accuracy. Furthermore, error performance over modulation bandwidth is dependent on the SCI setting.
For example modulations with relatively low frequency components and high crest factors may require higher SCI
(integration) settings.

For increased load drive capability, consider a buffer
amplier on the RMS output. Using an integrating
amplier on the RMS output allows for an alternative
treatment for faster settling times. An external
amplier optimized for transient settling can also
provide additional RMS ltering, when operating
HMC1010LP4E with a lower SCI value.
Following gures show how the peak-to-peak ripple
decreases with higher SCI settings along with the RF

LOG-Slope and Intercept
The HMC1010LP4 provides for an adjustment of output scale with the use of an integrated operational amplier.
Logslope and intercept can be adjusted to “magnify” a specic portion of the input sensing range, and to fully utilize
the dynamic range of the RMS output.
A log-slope of 37.3 mV/dB (@1900 MHz) is set by connecting RMS Output to VSET through resistor network for ß = 1
(see application schematic).
The log-slope is adjusted by applying the appropriate resistors on the RMS and VSET pins. Log-intercept is adjusted
by applying a DC voltage to the VSET pin.
Optimized slope = ß * log-slope
Optimized intercept = log-intercept – (RFBK /RSET) * VBLINE
RFBK
RFBK // RSHUNT // RSET
ß =
When RFBK=0 to set RMSOUT=VSET, then ß=1/2
If RSET is not populated, then ß = ½ * (RFBK/ (RFBK // RSHUNT)) and intercept is at nominal value.
Example: The logarithmic slope can be simply increased by choosing appropriate RFBK and RSHUNT values while
not populating the RSET resistor on the evaluation board to keep the intercept at nominal value.
Setting RFBK =4.7K and RSHUNT = 2.2K results in an optimized slope of:
Optimized Slope = ß * log_slope = 1.57* 37.3mV / dB
Optimized Slope = 58 mV / dB

DC Offset Compensation Loop
Internal DC offsets, which are input signal dependant, require continuous cancellation. Offset cancellation is a critical
function needed for maintenance of measurement accuracy and sensitivity. The DC offset cancellation loop performs
this function, and its response is largely dened by the capacitance (COFS) connected between COFSA, COFSB
pins.
COFS sets the loop bandwidth of the DC offset compensations. Higher COFS values are required for measuring
lower RF frequencies. The optimal loop bandwidth setting will allow internal offsets to be cancelled at a minimally
acceptable speed.
DC Offset Cancellation Loop ≈ Bandwidth , Hz
For example: loop bandwidth for DC cancellation with COFS = 1nF, bandwidth is ~62 kHz
Standby Mode
The ENX can be used to force the power detector into a low-power standby mode. As ENX is deactivated, power is
restored to all of the circuits. There is no memory of previous conditions. Coming-out of stand-by, internal integration
and COFS capacitors will require recharging, so if large SCI values have been chosen, the wake-up time will be
lengthened.
Modulation Performance – Crest factor performance
The HMC1010LP4E can detect modulated signals with very high crest factors accurately.
For example, up to 2.7 GHz, a modulated RF signal with a crest factor of 15 dB can be detected with 0.2 dB error.

System Calibration
Due to part-to-part variations in log-slope and log-intercept, a system-level calibration is recommended to satisfy
absolute accuracy requirements. When performing this calibration, choose at least two test points: near the top end
and bottom-end of the measurement range. It is best to measure the calibration points in the regions (of frequency
and amplitude) where accuracy is most important. Derive the log-slope and log-intercept, and store them in non-
volatile memory.
For example if the following two calibration points were measured at 2.2 GHz:
With RMSOUT = 2.321V at Pin= -5 dBm,
and RMSOUT = 0.809V at Pin= -45 dBm
slope calibration constant = SCC
SCC = (-45+5)/(0.809-2.321) = 26.45 dB/V
intercept calibration constant = ICC
ICC = Pin – SCC*RMSOUT = -5 – 26.45 * 2.321 = -66.39 dBm

Now performing a power measurement at -25 dBm:
RMSOUT measures 1.559V
[Measured Pin] = [Measured RMSOUT]*SCC + ICC
[Measured Pin] = 1.559*26.45 – 66.39 = -25.155 dBm
An error of only 0.155 dB
Factory system calibration measurements should be made using an input signal representative of the application. If
the power detector will operate over a wide range of frequencies, choose a central frequency for calibration.
Layout Considerations
• Mount RF input coupling capacitors close to the IN+ and IN- pins.
• Solder the heat slug on the package underside to a grounded island which can draw heat away from the die with
low thermal impedance. The grounded island should be at RF ground potential.
• Connect power detector ground to the RF ground plane, and mount the supply decoupling capacitors close
to the supply pins.
Denitions
• Log-slope: slope of PIN –> RMSOUT transfer characteristic. In units of mV/dB
• Log-intercept: x-axis intercept of PIN –> RMSOUT transfer characteristic. In units of dBm.
• RMS Output Error: The difference between the measured PIN and actual PIN using a line of best t.
[measured_PIN] = [measured_ RMSOUT] / [best-t-slope] + [best-t-intercept], dBm
• Input Dynamic Range: the range of average input power for which there is a corresponding RMS output
voltage with “RMS Output Error” falling within a specic error tolerance.
• Crest Factor: Peak power to average power ratio for time-varying signals.
