55-60GHz Low Noise / Medium Power Amplifier
GaAs Monolithic Microwave IC
Description
The CHA2157 is a two stage 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 grounded. This helps simplify the assembly process.
The circuit is manufactured with a pHEMT process, 0.15µm gate length, via holes through the substrate, air bridges and electron beam gate lithography.
It is available in chip form.
