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
