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.
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
