18-30GHz Low Noise Amplifier. GaAs Monolithic Microwave IC in SMD leadless package. The CHA2069-QDG is a three-stage self-biased wide band monolithic low noise amplifier. Typical applications range from telecommunication (point to point, point to multi-point, VSAT) to ISM and military markets. The circuit is manufactured with a standard pHEMT process: 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is supplied in lead-free SMD package.
