The KGF1175B is a small-signal amplifier, for frequencies ranging from the UHF-band to the Lband, that features low noise and low current operation. The KGF1175B specifications are guaranteed to a fixed matching circuit for 5 V and 850 MHz; external impedance-matching circuits are also required. Because of the one-input dual gate configuration, low noise, and low operating current, the KGF1175B is ideal as a receiving-stage head amplifier for personal handy phones.
