The KGF1146 is a two-stage small-signal UHF-band amplifier that features low current operation, high output power, and high isolation. The KGF1146 specifications are guaranteed to a fixed matching circuit for 5 V and 850 MHz; external impedance-matching circuits are also required. Because of the high isolation, the KGF1146 is an ideal part for a VCO-buffer amplifiers and an intermediate-stage amplifier for personal handy phones, such as cellular phones.
