HMC526

GaAs MMIC I/Q MIXER

6 - 10 GHz

v00.1204

General Description

Features

Typical Applications

The HMC526 is a compact I /Q MMIC mixer which can

be used as either an Image Reject Mixer 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 USB IF output. This product is a much

smaller alternative to hybrid style Image Reject Mixers

and Single Sideband Upconverter assemblies.
