The KGF2441 is a GaAs FET AGC amplifier offering a wide dynamic range of ³80 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 mas portable handy phones based on CDMA-type digital cellular technology operating over wide dynamic ranges.
