CHU3377
RoHS COMPLIANT
W-band Multifunction: Multiplier / MPA
GaAs Monolithic Microwave IC
Description
The CHU3377 is a W-band monolithic
multifunction, which integrates an input buffer, a
frequency multiplier by three followed by an
amplifier splitter and two W-band chains in
parallel combined at the output. Each W-band
chain includes a frequency multiplier and a
medium power amplifier. The frequency
multipliers are based on active transistors and
allow operation at low input level with reduced
power consumption.
All the active devices are internally self-biased
to ease bias configuration. This chip is
compatible with automatic equipment for
assembly.
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.
