1998 KGF1254B/1254 ¡ electronic components 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 PACKAGE DIMENSIONS 1.
