HMC524LC3B
v03.0514
GaAs MMIC I/Q MIXER
22 - 32 GHz
General Description
FeaturesTypical Applications
The HMC524LC3B is a compact I/Q MMIC mixer
which can be used as either an Image Reject Mixer
or a Single Sideband Upconverter. The chip utilizes
standard Hittite mixer cells and a 90 degree hybrid
fabricated in a GaAs MESFET process. A low
frequency quadrature hybrid was used to produce
a 100 MHz USB IF output. This product is a much
smaller alternative to hybrid style Image Reject mixers
and single sideband upconverter assemblies. The
HMC524LC3B eliminates the need for wirebonding,
allowing the use of surface mount techniques.

Evaluation PCB
The circuit board used in the 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 sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation circuit board shown is available from Hit-
tite upon request.
