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.)
