KGF1156
Small-Signal Amplifier
GENERAL DESCRIPTION
The KGF1156 is a small-signal UHF-band amplifier that features high output power, high gain,
low noise, and low current operation. The KGF1156 specifications are guaranteed to a fixed
matching circuit for 5 V and 850 MHz; external impedance-matching circuits are also required.
Because of the dual gate configuration, high output, high gain, low noise, and low operating
current, the KGF1156 is ideal as a receiver mixer for personal handy phones.
FEATURES
• High output power: 6 dBm (min.)
• High linear gain: 15 dB (min.)
• Low current operation: 6 mA (max.)
• Low noise: 3 dB (max.)
• Self-bias circuit configuration with built-in source capacitor
• Package: 4PSOP
