KGF1256B/1256

Medium-Power Amplifier

GENERAL DESCRIPTION

The KGF1256B is a medium-power amplifier, with frequencies ranging from the UHF-band to

the L-band, that features high output power, low noise, and low current operation. The

KGF1256B specifications are guaranteed to a fixed matching circuit for 5 V and 850 MHz; external

impedance-matching circuits are also required. Because of the low noise and high output power

at the low operating current, the KGF1256B is ideal as a transmitter-driver amplifier for personal

handy phones.

The KGF1256 is similar to the KGF1256B in specifications and typical properties. Although

having S Parameters that are slightly different from those of the KGF1256B, the KGF1256 meets

the specifications for the KGF1256B, even with the same matching circuits.

FEATURES

• High output power: 15 dBm (min.)

• Low noise: 2.5 dB (max.)

• Low current: 40 mA (max.)

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

• Package: 4PSOP
