Hi We are working out the plan for the developmen of QPSK and 8 PSK demodulators for 480 MHz band width (Base band data) and carrier frequency (IF) of 720 MHz. The ADRF6820 IC felt meets the zero IF concersion requirement but in confusion, how to use it? Mean time, came to know that this IC is not recommending for new designs? So is there any alternate suitable IC? If so pl provide the details at the earliest.
