KGF1254B/1254

Medium-Power Amplifier

GENERAL DESCRIPTION

The KGF1254B 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

KGF1254B specifications are guaranteed to a fixed matching circuit for 5.2 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 KGF1254B is ideal as a transmitter-driver

amplifier for personal handy phones.

The KGF1254 is an amplifier similar to the KGF1254B in specifications and typical properties.

Although having S Parameters that are slightly different from those of the KGF1254B, the

KGF1254 meets the specifications for the KGF1254B, even with the same matching circuits as

those of the KGF1254B.
