MGCM01

The inputs for the receive path are I and Q signals at an IF of 60kHz. The I and Q signals are filtered by a 60kHz switched capacitor bandpass filter and are then demodulated to give baseband I and Q signals. The MGCM01 also provides voltage gain so that the baseband outputs can be input directly to an A to D converter.The internal FM discriminator can be used for demodulating AMPS signals; the receive path also provides RSSI.

Transmit I and Q baseband signals from D to A converters can be input directly to the MGCM01, which provides reconstruction filters and a variable gain buffer.The two PLL synthesisers are used for generation of the receive and transmit IF LO signals.
