CHA7115-99F
RoHS COMPLIANT
X-band High Power Amplifier
GaAs Monolithic Microwave IC
Description
Vg3 Vd3
The CHA7115 is a monolithic three-stage
GaAs high power amplifier designed for
X-band applications.
Vg2 Vd2
Vg1
The HPA provides typically 8W output power
associated to 36% power added efficiency at IN
