The KGF1181B is a two-stage medium-power UHF-band amplifier that features high gain, high output power, and low power operation. 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.
