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 applicati...
