Description
The HMMC-5618 6–20 GHz MMIC is an efficient two-stage amplifier that is designed to be used as a cascadable intermediate gain block for EW applications. In communication systems, it can be used as an amplifier for a local oscillator, or as a transmit amplifier. It is fabricated using a PHEMT integrated circuit structure that provides exceptional efficiency and flat gain performance. During typical operation, with a single 5-volt DC power supply, each gain stage is biased for Class-A operation for optimal power output with minimal distortion. The RF input and RF output has matching circuitry for use in 50␣ ohm environments.
