CHA2080-98F
71-86GHz Low Noise Amplifier
GaAs Monolithic Microwave IC
Description
The CHA2080-98F is a Low Noise Amplifier
with variable gain. This circuit integrates four
stages and provides 3.5dB Noise Figure
associated to 22dB Gain and +10dBm
Output Power at 1dB compression.
This amplifier is dedicated to
telecommunication, particularly well suited for
the two main E-Bands used in new
generation of High Capacity Backhaul.
It is manufactured with a pHEMT process,
0.1µm gate length, via holes through the
substrate, air bridges, electron beam gate
lithography and is available in chip form with
BCB Layer protection.
