KGF1265
Medium-Power Amplifier
GENERAL DESCRIPTION
The KGF1265 is a medium-power amplifier, with frequencies ranging from the UHF-band, that
features high output power, low distortion, and low current operation. The KGF1265 specifi-
cations are guaranteed to a fixed matching circuit for 3 V and 900 MHz band; external impedance-
matching circuits are also required. Because of the high output power and low distortion at the
low operating current, the KGF1265 is ideal as a transmitter-driver amplifier for portable phones
such as PDC and CDMA.
FEATURES
• High output power: 11 dBm (min.)
• Low voltage and low current operation: 3 V, 18 mA (max.)
• Low distortion (ACP): –55 dBc (max) @P_O = 8dBm, p/4DQPSK, ±50 kHz
• Self-bias circuit configuration with built-in source capacitor
• package: 4PSOP
