The CLC5526 is a high performance, digitally controlled, variable-gain amplifier (DVGA). It has been designed for use in a broad range of mixed signal and digital communication applications such as mobile radio, cellular base stations and back-channel modems where automatic-gain-control (AGC) is required to increase system dynamic range. The CLC5526 has differential input and output, allowing large signal swings on a single 5V rail. The input impedance is 200. The differential output impedance is 600 and is designed to drive a 1 k differential load. The output amplifier has excellent intermodulation performance. The CLC5526 is designed to accept signals from RF elements and maintain a terminated impedance environment. The CLC5526 maintains a 350 MHz bandwidth over its entire gain and attenuation range from +30 dB to -12 dB. Internal clamping ensures very fast overdrive recovery. Two tone intermodulation distortion is excellent: at 150 MHz, 1 Vpp it is -64 dBc.
