Previous version: Jan. 1998
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
