KGF1183

Medium-Power Amplifier

GENERAL DESCRIPTION

The KGF1183 is a two-stage medium-power UHF-band amplifier that features high gain and

high output power. The internally matched 50 W input eliminates external impedance-matching

circuits for the input, but it requires a simple matching circuit for the output. All specifications

for this device are guaranteed at 5 V and 850 MHz. Because of the high gain and high output

power, the KGF1183 is ideal as a transmitter-intermediate-stage amplifier for personal handy

phones.
