The HMC1097LP4E's excellent noise and linearity performance makes it suitable for a wide range of transmission standards, including single and multicarrier CDMA, UMTS, CDMA2000, GSM/EDGE, W-CDMA, TDSCDMA, and WiMAX/LTE applications. As shown in the simplified block diagram (Figure 1) the HMC1097LP4E offers an easy-to-use, complete direct conversion solution in a highly compact 4 x 4 mm plastic package thereby reducing cost, area, and power consumption. The HMC1097LP4E modulator consists of the following functional blocks: 1. LO Interface: High Accuracy LO quadrature phase splitter and LO limiting amplifiers 2. I/Q modulator: I and Q input differential voltage-to-current converters, I and Q upconverting mixers and the differential-to-single-ended converter 3. Bias and Enable/Disable Circuits LO Interface The LO interface consists of a LO quadrature phase splitter that generates two carrier signals in quadrature followed by LO limiting amplifiers which are used to drive the I and Q mixers with saturated signal levels. Therefore, the LO path is immune to large variations in the LO input signal level and the modulator performance does not vary much 11 For price, delivery and to place orders: Hittite Microwave Corporation, 2 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com Application Support: Phone: 978-250-3343 or apps@hittite.com HMC1097LP4E v03.0812 WIDEBAND DIRECT QUADRATURE MODULATOR, 100 - 6000 MHz with LO input power. The LO input impedance is set by the LO quadrature phase splitter. The LO port can be driven differentially with 100 differential input impedance or single ended through LON input with 50 input impedance while the unused LOP input should be terminated to GND through 50. The LO port requires -6 to +6 dBm input power in either differential or single-ended mode and does not require DC blocking capacitors. The differential baseband inputs (QP, QN, IP, and IN) present a high impedance. The DC common-mode voltage at the baseband inputs sets the currents in the I and Q double-balanced mixers. The nominal baseband input DC common-mode voltage used in the characterization of the HMC1097LP4E is 0.45V, which should be externally applied. The baseband input DC common-mode voltage can be varied between 0.4V and 0.5V to optimize overall modulator performance. It is not recommended to leave the baseband inputs floating which generates excessive current flow that may cause damage to the IC. The baseband inputs should be pulled down to GND in shutdown mode. The nominal baseband input AC Voltage used in the characterization of the HMC1097LP4E is 1.3Vpp differential. The baseband input AC voltage can be varied to optimize overall modulator performance. It is recommended to drive the baseband inputs differentially to reduce even-order distortion products and also use reconstruction filters at the baseband inputs to avoid aliasing After upconversion, the outputs of the I and Q mixers are summed together differentially and converted to singleended RF output. The single-ended RF output port is internally matched to 50 Ohms and does not require any external matching components. Only a standard DC-blocking capacitor is required at this interface. Bias and Enable/Disable Circuits A bandgap reference circuit generates the reference currents used by the different sections. The part requires a single supply voltage of +5V to operate. The EN pin can be used to disable the bandgap reference circuit. Disabling the bias circuit will also disable the reference currents to the LO limiting amplifiers,I and Q mixers and the output stage. If the EN pin is connected to ground or left floating, the part operates normally. If the EN pin is connected to the +5V VCC, the LO limiting amplifiers, I and Q mixers and the output stage are disabled and the LO leakage is also reduced. The LO signal itself is suppressed approximately by 57.1 dB at 2.1GHz when the EN pin is connected to the +5V VCC. The enable and disable settling times are approximately 400 ns. MODS & DEMODULATORS - SMT I/Q Modulator Carrier Feedthrough Calibration Carrier feedthrough is related to the dc offsets at the differential baseband inputs of the modulator. If exactly the same DC common-mode voltage is applied to each of the baseband inputs and there were no dc offsets at the differential baseband inputs, the LO leakage at the RF output would be perfectly suppressed. By adding small DC offset voltages at the differential baseband inputs, the carrier feedthrough can be optimized for a specific frequency band and LO power level. The carrier feedthrough can not be calibrated by the DC commonmode level at the I and Q baseband inputs. DC offsets at the differential I and Q baseband inputs should be iteratively adjusted until a minimum carrier feedthrough level is obtained. Externally available offset voltage steps and the modulator's noise floor limit the minimum achievable calibrated carrier feedthrough level. The typical offset voltages for optimization are less than 15mV. Figure 2 illustrates the typical calibrated carrier feedthrough performance of the HMC1097LP4E. In this characterization of the HMC1097LP4E, carrier feedthrough was calibrated with 500MHz LO frequency steps at 25C and external offset voltage settings were held constant during tests over temperature. For instance, the required the Q channel offset is 2mV and the I channel offset is -3mV at 2.5GHz.

The amplitude and phase difference between the I and Q inputs can be adjusted in order to optimize the sideband suppression for a specific frequency band and LO power level. The amplitude and phase offsets at the I and Q inputs should be iteratively adjusted until a minimum sideband suppression level is obtained. The externally available amplitude and phase steps and the modulator's noise floor limit the minimum achievable calibrated sideband suppression level. Figure 3 illustrates the typical calibrated sideband suppression performance of the HMC1097LP4E. In this characterization of the HMC1097LP4E, sideband suppression was calibrated with 500MHz LO frequency steps at 25C and external amplitude and phase offset settings were held constant during tests over temperature. For instance, gain imbalance is equal to -0.03dB and phase imbalance is equal to -0.25deg at 2.5GHz. 0 SIDEBAND SUPPRESSION (dBc) MODS & DEMODULATORS - SMT 11 +25C +85C -40C -10 -10 +25C +85C -40C -20 -30 -40 -50 -60 -70 -80 -90 -100 0 1000 2000 3000 4000 5000 6000 FREQUENCY (MHz) Figure 3: The HMC1097LP4E Calibrated Sideband Suppression Linearity Optimization Output IP3 (OIP3) of the HMC1097LP4E depends on the DC common-mode level at the I and Q baseband inputs. The DC common-mode level at the I and Q baseband inputs can be adjusted in order to optimize the OIP3 for a specific frequency band. Figure 4 illustrates the typical relationship between OIP3 and the DC common-mode level at the I and Q baseband inputs for different LO frequencies. As shown in Figure 4, OIP3 of the HMC1097LP4E can be optimized up to 35dBm. 13 For price, delivery and to place orders: Hittite Microwave Corporation, 2 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com Application Support: Phone: 978-250-3343 or apps@hittite.com HMC1097LP4E v03.0812 WIDEBAND DIRECT QUADRATURE MODULATOR, 100 - 6000 MHz 50 45 35 30 25 20 15 450 MHz 900 MHz 1900 MHz 2600 MHz 3500 MHz 10 5 0 0.35 0.4 0.45 0.5 0.55 BASEBAND VOLTAGE (V) Figure 4: The HMC1097LP4E Linearity Optimization GSM/EDGE Operation The HMC1097LP4E is suitable for GSM/EDGE applications.

Figure 7 shows the adjacent and alternate channel power ratios for the HMC1097LP4E at an LO frequency of 2140 MHz. The HMC1097LP4E is able to deliver about -73 dBc ACPR and -80 dBc AltCPR at an output power of -10 dBm. ACPR and AltCPR performances of the HMC1097LP4E can be improved by adjusting the DC common-mode level on the I and Q baseband inputs. -30 ACPR and AltCPR (dB) -40 ACPR AltCPR -50 -60 -70 -80 -90 -30 -25 -20 -15 -10 -5 0 OUTPUT POWER dBm) Figure 7: The HMC1097LP4E ACPR and AltCPR vs. Output Power @ WCDMA LTE Operation The HMC1097LP4E is suitable for LTE applications.
