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.
FEATURES
• Internally matched 50 W input
• High linear gain: 20 dB (min.)
• High output power: 17 dBm (min.)
• Low current operation: 80 mA (max.)
• Self-bias circuit configuration with built-in source capacitor
• Package: 4PSOP
