HMC523LC4
GaAs MMIC I/Q MIXER
15 - 23 GHz
v00.0405
General Description
Features
Typical Applications
The HMC523LC4 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
HMC523LC4 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 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 cir-
cuit board shown is available from Hittite upon
request.
