The internally matched 50 W input and output eliminate external impedance-matching circuits. All specifications for this device are guaranteed at 5 V and 850 MHz. Because of the high gain and high output power, the KGF1181B is ideal as a transmitter-intermediate-stage amplifier for personal handy phones. FEATURES Internally matched 50 W input and output High linear gain: 20 dB (min.) High output power: 11.5 dBm (min.) Low current operation: 40 mA (max.)
