The HMC528LC4 is a compact general purpose
I/Q MMIC mixer in a leadless RoHS compliant 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 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 HMC528LC4 eliminates
the need for wire bonding allowing use of surface
mount manufacturing techniques.

Evaluation PCB
The circuit board used in the fi 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 con-
nected 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.
