UMS CHA2157

CHA2157
55-60GHz Low Noise / Medium Power Amplifier
GaAs Monolithic Microwave IC
Description
The circuit is manufactured with a HEMT
process, 0.15µm gate length, via holes through
the substrate, air bridges and electron beam
gate lithography.
It is available in chip form.
Main Features
3.5 dB noise figure
10 dB ± 1dB gain
15 dBm output power (-1dB gain comp.)
DC power consumption, 80mA @ 3.3V
Chip size : 1.71 x 1.04 x 0.10 mm
Gain & Rloss (dB)
The CHA2157 is a two stages low noise and
medium power amplifier. It is designed for a
wide range of applications, from military to
commercial
communication
systems. The
backside of the chip is both RF and DC grounds.
This helps simplify the assembly process.
