Small-Signal Amplifier
GENERAL DESCRIPTION
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 the high gain and high isolation at 3 V, the KGF1191 is ideal as an intermediate-stage amplifier for portable phones.
FEATURES
* Low voltage and low current: 3 V, 5 mA (max.) * Specifications guaranteed to a fixed matching circuit for 3 V and 850 MHz * High linear gain: 24 dB (typ.) * High isolation: -35 dB (typ.) * Self-bias circuit configuration with built-in source capacitor * Package: 4PSOP
