Description

Agilent’s AMMC- 5618 6−20 GHz MMIC is an efficient two- stage amplifier designed to be used as

a cascadable intermediate gain block for EW applications. In communication systems, it can be used as a LO buffer, or as a transmit driver 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- V supply, each gain stage is biased for Class- A operation for optimal power output with minimal distortion. The RF input and output have matching circuitry for use in

50-Ωenvironments. The backside of the chip is both RF and DC ground. This helps simplify the assembly process and reduces assembly related performance variations and costs. The MMIC is a cost effective alternative to hybrid (discrete FET) amplifiers that require complex tuning and

assembly processes.
