The AD6432 IF IC provides the complete transmit and receive IF signal processing, including I/Q modulation and demodulation, necessary to implement a digital wireless transceiver such as a GSM handset. The AD6432 may also be used for other wireless TDMA standards using I/Q modulation. The AD6432’s receive signal path is based on the proven architecture of t.
