GaAs MMIC I/Q MIXER
11 - 16 GHz
General Description
FeaturesTypical Applications
The HMC522LC4 is a compact I/Q MMIC mixer in a
leadless “Pb free” SMT package, which can be used
as either an Image Reject Mixer or a Single Sideband
Upconverter. The mixer utilizes two standard Hittite
double balanced mixer cells and a 90 degree hybrid
fabricated in a GaAs MESFET process. A low freq-
uency 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
HMC522LC4 eliminates the need for wire bonding
allowing use of surface mount manufacturing
techniques.

13, 17 - 24 N/C No connection required. These pins may be connected
to RF/DC ground without affecting performance.
3, 5, 12, 14, 16 GND These pins and package bottom must
be connected to RF/DC ground.
4RF This pin is AC coupled and matched to
50 Ohms from 11 to 16 GHz.
9IF1
This pin is DC coupled. For applications
not requiring operation to DC, this port should be
DC blocked externally using a series capacitor whose
value has been chosen to pass the necessary IF
frequency range. For operation to DC, this pin must not
source/sink more than 3mA of current or part non-func-
tion and possible part failure will result.

15 LO This pin is AC coupled and matched to
50 Ohms from 11 to 16 GHz.

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.
