Previous version: Jan. 1998
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.
FEATURES
High output power: 20 dBm (min.)
Low noise: 2.5 dB (max.)
Low current operation: 80 mA (max.)
Self-bias circuit configuration with built-in source capacitor
Package: 4PSOP
PACKAGE DIMENSIONS
