KGF1146

Small-Signal Amplifier

GENERAL DESCRIPTION

The KGF1146 is a two-stage small-signal UHF-band amplifier that features low current opera-

tion, high output power, and high isolation. The KGF1146 specifications are guaranteed to a fixed

matching circuit for 5 V and 850 MHz; external impedance-matching circuits are also required.

Because of the high isolation, the KGF1146 is an ideal part for a VCO-buffer amplifiers and an

intermediate-stage amplifier for personal handy phones, such as cellular phones.

FEATURES

• Low current operation: 2.5 mA (max.)

• High output power: 1.5 dBm (min.)

• High isolation: –40 dB

• Self-bias circuit configuration with built-in source capacitor

• Package: 4PSOP
