DEMODULATORS - SMT

HMC597LP4 / 597LP4E
v06.0613
SiGe WIDEBAND DIRECT
DEMODULATOR RFIC, 100 - 4000 MHz
General Description
Features
Functional Diagram
The HMC597LP4(E) are highly integrated SiGe
wideband direct conversion I/Q Demodulator RFICs
which are ideal for high dynamic range receivers
operating from 100 - 4000 MHz in cellular and
broadband wireless infrastructure applications.
Providing a very high level of integration compared
with discrete solutions, the HMC597LP4(E) features an
on-chip RF balun which allows for singled ended RF
input. An off-chip capacitor allows the reconīguration
of the RF port to operate over the whole 100 - 4000
MHz band without additional off-chip components.
Also ideal for software radio and other multi-band
receivers, the HMC597LP4(E) demodulator is housed
in a compact 4 x 4 mm SMT QFN package and delivers
exceptionally high dynamic range. The LO requires -6
to +6 dBm and can be driven in single-ended mode.
The I and Q output ports are differential with an output
impedance of 400 Ohms, allowing direct connection to
channel īlters and ADCs. This device is optimized for
a supply voltage of +4.5V to +5.5V and consumes 200
mA @ +5V supply.
High Linearity: +25 dBm IIP3 & +60 dBm IIP2
Low Noise Figure: 15 dB
High Integration: On-Chip RF Balun
Typical Applications
The HMC597LP4 / HMC597LP4E is suitable for
various modulation systems:
ā¢ Cellular/PCS/3G
ā¢ Base Stations & Repeaters
ā¢ GSM/GPRS, WCDMA & TD-SCDMA
ā¢ WiMAX, WiBro & Fixed Wireless

Evaluation PCB
The circuit board used in the īnal application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation circuit board shown is available from
Hittite upon request.
