CHA6518
RoHS COMPLIANT
5 - 18 GHz High Power Amplifier
GaAs Monolithic Microwave IC
Description
The
CHA6518
is a monolithic three-stage
GaAs high power amplifier designed for wide
band applications.
This device is manufactured using a UMS
0.25 µm Power pHEMT process, including,
via holes through the substrate and air
bridges.
To simplify the assembly process:
•
the backside of the chip is both RF and
DC grounded
•
bond pads and back side are gold plated
for compatibility with eutectic die attach
method
and
thermosonic
or
thermocompression bonding process.
