CHM2378a

W-band Dual Channel Mixer

GaAs Monolithic Microwave IC

Description

RF1

RF2

The CHM2378 is a dual channel mixer.

Each mixer cell is a balanced structure

based on a six quarter wave ring. The non-

linear devices are high quality Schottky

diodes providing low conversion loss and

very low 1/f noise.

This circuit is manufactured with the BES-

MMIC process: 1 µm Schottky diode

device, air bridges, via holes through the

substrate, stepper lithography.
