HMC520LC4
v03.0514
GaAs MMIC I/Q MIXER
6 - 10 GHz
General Description
FeaturesTypical Applications
The HMC520LC4 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 frequ-
ency 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
HMC520LC4 eliminates the need for wire bonding
allowing use of surface mount manufacturing
techniques.

9IF1
This pin is DC coupled. For applications not requir-
ing 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-function and possible
part failure will result.

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
Hittite upon request.
