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
