CHU2277a
RoHS COMPLIANT
W-band Multifunction : Multiplier / MPA
GaAs Monolithic Microwave IC
Description
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 to operate at low input
level with a 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.
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.

This drawing shows an example of assembly and bias configuration. All the
transistors are internally self biased. An external capacitor is recommended for the
positive and negative supply voltages.
For the RF pads the equivalent wire bonding inductance (diameter=25µm) have to
be according to the following recommendation.
