Features

General Description

The HMC572 is a compact GaAs MMIC I/Q

downconverter chip which provides a small signal

conversion gain of 8 dB with a noise fi gure of 3.5 dB

and 20 dB of image rejection across the frequency

band. The device utilizes an LNA followed by an image

reject mixer which is driven by an active x2 multiplier.

The image reject mixer eliminates the need for a fi lter

following the LNA, and removes thermal noise at the

image frequency. I and Q mixer outputs are provided

and an external 90° hybrid is needed to select the

required sideband. All data shown below is taken

with the chip mounted in a 50 Ohm test fi xture and

includes the effects of 1 mil diameter x 20 mil length

bond wires on each port. This product is a much

smaller alternative to hybrid style image reject mixer

downconverter assemblies.
