CHA6005-99F
Linear Gain (dB) & Pout @ ~ 3dBcomp Idrain @ ~ 3dBcomp (mA)
8-12GHz High Power Amplifier
GaAs Monolithic Microwave IC
Description
The CHA6005-99F is a high power amplifier monolithic circuit, which integrates two stages and produces 32.5dBm output power associated to a high power added efficiency of 38%. It is designed for a wide range of applications, from military to commercial communication systems. The circuit is manufactured with a pHEMT process, 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is available in chip form.

These values are representative of on-wafer measurements that are made without bonding wires at the RF ports.
A bonding wire of typically 0.25 to 0.3nH will improve the matching at the accesses.
