    ADC driver for 10-bit to 14-bit GSPS converters RF/IF gain blocks Line drivers Instrumentation Satellite communications Data acquisition Military systems GENERAL DESCRIPTION
    The ADA4961 is a high performance, BiCMOS RF digital gain amplifier (DGA), optimized for driving heavy loads out to 2.0 GHz and beyond. The device typically achieves -90 dBc IMD3 performance at 500 MHz and -85 dBc at 1.5 GHz. This RF performance allows GHz converters to achieve their optimum performance with minimal limitations of the driver amplifier or constraints on overall power that typically result from GaAs amplifiers. This device can easily drive 10-bit to16-bit HS converters. For many receiver applications, antialias filter (AAF) designs can be simplified or not required. The ADA4961 has an internal differential input impedance of 100 and a differential dynamic output impedance of 50 , eliminating the need for external termination resistors. The

Technical Support www.analog.com digital adjustability provides for 1 dB resolution, thus optimizing the signal-to-noise ratio (SNR) for input levels spanning 21 dB. The ADA4961 is optimized for wideband, low distortion performance at frequencies up to 2 GHz. These attributes, together with wide gain adjustment and relatively low power, make the ADA4961 the amplifier of choice for many high speed applications, including IF, RF, and broadband ...
