Description
The HMMC-5618 6–20 GHz
MMIC is an efficient two–stage
medium-power amplifier that is
designed to be used as a cascad-
able intermediate gain block for
EW applications. In communica-
tion systems, it can be used as
an amplifier for a local oscillator
or as a transmit amplifier. It is
fabricated using a PHEMT inte-
grated circuit structure that
provides exceptional efficiency
and flat gain performance. Dur-
ing typical operation, with a sin-
gle 5–volt DC power supply,
each gain stage is biased for
Class–A operation for optimal
power output with minimal dis-
tortion. The RF input and RF
output has matching circuitry
for use in 50 ohm 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.
