RFHIC Introduces GaAs p-HEMT LNA for S-Band Applications
Alumina ceramic substrate based GaAs p-HEMT LNA
April 2, 2010 - RFHIC, a manufacturer of gallium nitride and gallium arsenide active RF Microwave components
and hybrid modules, announces the release of ceramic substrate based GaAs p-HEMT Hybrid LNA (Low Noise Amplifier)
that can be well suited to S-band applications.
These Low Noise Amplifiers are built with GaAs
p-HEMT die attached on a ceramic thick film substrate. Alumina, the most commonly used type of ceramic, is what
RHIC has chosen due to its relatively high thermal conductivity. These Low Noise Amplifiers are focused on giving
the lowest noise possible; exhibiting low noise performance of better than 1dB noise figure. The devices work at
input levels as high as 20dBm thanks to the initial gate length of 1200µm design.

Limiter diode inclusive version will work even at 30dBm input levels.
