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.
Main Features

Example of integration using low dielectric constant substrate : Er=2.2,
heigh=0.127mm (dimensions are in mm)
In order to use acceptable wire bonding length, an external matching network is
proposed for the LO input on low dielectric constant substrat.
