Description
The HMMC-5618 66 to 20 GHz MMIC is
an efficient two-stage medium-power
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 ?
environments.
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.
