GENERAL DESCRIPTION
TDA8060ATS Accurate QPSK demodulation is ensured by the on-chip loop-controlled phase shifter. The Zero-IF concept discards traditional IF filtering and intermediate conversion techniques. It also simplifies the signal path. The baseband I and Q signal bandwidth only depends, to a certain extent, on the external filter used in the application. Optimum signal level is guaranteed by a gain-controlled amplifier at the RF input. The pin AGC sets the gain for both I and Q channels, providing a 37 dB range. The chip also offe...
