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
wit h d is cr et e s ol ut io ns, the H MC 59 7L P4( E) fe at ur es an
on-chip RF balun which allows for singled ended RF
input. An off-chip capacitor allows the recon guration
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 lters and ADCs. This device is optimized for
a supply voltage of +4.5V to +5.5V and consumes 200
mA @ +5.0V supply.

The circuit board used in the nal application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be connected directly to the ground plane similar to that
shown. A suf cient 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.
