SiGe WIDEBAND DIRECT
DEMODULATOR RFIC, 100 - 4000 MHz
Typical Applications
The HMC597LP4 / HMC597LP4E is suitable for
various modulation systems:
• Cellular/PCS/3G
• Base Stations & Repeaters
• GSM/GPRS, WCDMA & TD-SCDMA
• WiMAX, WiBro & Fixed Wireless
Features
High Linearity: +25 dBm IIP3 & +60 dBm IIP2
Low Noise Figure: 15 dB
High Integration: On-Chip RF Balun
General Description
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 reconfiguration
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 filters and ADCs. This device is optimized for
a supply voltage of +4.5V to +5.5V and consumes 200
mA @ +5V supply.
