HMC620

GaAs MMIC I/Q MIXER

3 - 7 GHz

v01.1007

General Description

Features

Typical Applications

The HMC620 is a compact I/Q MMIC mixer which can

be used as either an Image Reject Mixer (IRM) or a

Single Sideband Upconverter. The chip utilizes two

standard Hittite double balanced mixer cells and a 90

degree hybrid fabricated in a GaAs MESFET process.

All data shown below is taken with the chip mounted

in a 50 Ohm test fixture and includes the effects of

1 mil diameter x 20 mil length bond wires on each

port. A low frequency quadrature hybrid was used to

produce a 100 MHz upper side band (USB) IF output.

This product is a much smaller and more consistent

alternative to hybrid style Image Reject Mixers and

Single Sideband Upconverter assemblies.
