CDMA 3 V Receiver IF Subsystem with Integrated Voltage Regulator

The AD6121 is a low power receiver IF subsystem specifically designed for CDMA applications. It consists of high dynamic range IF amplifiers with voltage controlled gain, a divide-by-two quadrature generator, an I and Q demodulator, and a power-down control input. An integral low dropout regulator allows operation from battery voltages from 2.9 V to 4.2 V.
