KGF2441

AGC Amplifier

GENERAL DESCRIPTION

The KGF2441 is a GaAs FET AGC amplifier offering a wide dynamic range of ≥80 dB. With

control over a +30 dB (max.) to –50 dB (min.) range at 130 MHz, the device also provides excellent
gain slope linearity. The KGF2441 operates with a single 5-V power supply with a low current
operation of 5 mA (typ.) The device is particularly suited to IF-stage amplifier applications, such
as portable handy phones based on CDMA-type digital cellular technology operating over wide
dynamic ranges.

FEATURES

• Wide dynamic range: 80 dB (min.)

• Excellent gain slope linearity for AGC voltage

• Low current operation: 5 V, 5 mA (typ.)

• Package: 8PSOP
