The KGF1191 is a two-stage small-signal amplifier, with frequencies ranging from the UHF-band to the L-band, that features low voltage operation, low current operation, high gain, and high isolation. The KGF1191 specifications are guaranteed to a fixed matching circuit for 3 V and 850 MHz; external impedance-matching circuits are also required. Because of th.
low voltage operation, low current operation, high gain, and high isolation. The KGF1191 specifications are guaranteed to a fixed matching circuit for 3 V and 850 MHz; external impedance-matching circuits are also required. Because of the high gain and high isolation at 3 V, the KGF1191 is ideal as an intermediate-stage amplifier for portable phones.
