RoHS COMPLIANT
W-band Multifunction: Multiplier / MPA
GaAs Monolithic Microwave IC
Description

OUT1
The CHU2277a is a W-band monolithic
multifunction which integrates a frequency
multiplier, a four-stage amplifier and a power
divider. The frequency multiplier is based on
an active transistor and allows operating at
low input level with reduced power
consumption. This chip provides two outputs
at 77GHz, the main one is for the
transmission path and the auxiliary one for
the receiving mixer(s) LO signal. All the
active devices are internally self-biased. This
chip is compatible with automatic equipment
for assembly.

OUT2
The circuit is manufactured with the P-HEMT
process: 0.15µm gate length, via holes
through the substrate, air bridges and
electron beam gate lithography.
It is available in chip form.
