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 specifications are guaranteed to a fixed matching circuit for 3 V and 900 MHz band; external impedancematching 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) @PO = 8dBm, π/4DQPSK, ±50 kHz

• Self-bias circuit configuration with built-in source capacitor

• package: 4PSOP
