CHA5093
22-26GHz High Power Amplifier
GaAs Monolithic Microwave IC Description
The CHA5093 is a high gain three-stage monolithic high 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. The circuit is manufactured with a PM-HEMT process, 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is available in chip form.

Application note
CHA5093
The given DC Bias condition in table or curves are for optimum output power. To optimize the gain a drain voltage of 5V could be apply. With this biasing point , the output power at 1dB compression decreases by around 1dBm. The curves below show typical jig measurements versus drain & gate voltages.
