CHA2266 RoHS COMPLIANT 12.5-17GHz Low-Noise Driver Amplifier GaAs Monolithic Microwave IC Description VD 1 The CHA2266 is a self biased, low-noise high gain driver amplifier. It is designed mainly for VSAT applications in Kuband. The backside of the chip is both RF and DC grounded. This helps to simplify the assembly process. The circuit is manufactured on a standard GaAs pHEMT process, with via holes through the substrate, air bridges and electron beam gate lithography. It is available in chip form.
