General description

The TDA9935 is optimized to reduce architecture complexity and overall system cost. Thanks to its direct IF conversion capabilities, it leads dynamic performance in multi-carrier support. With an internal sampling rate up to 160 Msample/s, TDA9935 is an extremely competitive solution for WCDMA, CDMA2000 and GSM/EDGE transmitters, as well as high data rate radio services like WLL, LMDS and BWA.
