CHA2293 24.5-29.5GHz Low Noise, Variable Gain Amplifier GaAs Monolithic Microwave IC Description The CHA2293 is a high gain four-stage monolithic low noise amplifier with variable gain. 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 grounded. 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.
