CHM2179a
W-band Mixer
GaAs Monolithic Microwave IC
Description
The CHM2179a is a balanced Schottky
diode mixer based on a six quarter wave
ring structure. This circuit is manufactured
with the BES-MMIC process: 1 µm
Schottky diode device, air bridges, via
holes through the substrate, stepper
lithography.
It is available in chip form.

CHM2179a
Typical Assembly and RF Configuration
In order to use acceptable wire bonding length, compatible with automatic
pick and place and wire bonding equipment, an external matching network is
proposed on low dielectric constant substrate.
