K Band Mixer

GaAs Monolithic Microwave IC

Description

The CHM1191 is a balanced Schottky

diode mixer based on a six quarter wave

ring structure. It could be use in receiver or

transmitter part.

This circuit is manufactured with the BES-

MMIC process:

1 µm

Schottky diode

device, air bridges, via holes through the

substrate, stepper lithography.

An electrically identical chip with a mirror

drawing versus de LO side is available

under the part number CHM1190. These

two MMICs could be helpful in a TX, RX

architecture module.

It is available in chip form.
