IF Receivers take a 70 MHz input and demodulate the information in the data stream. Formats demodulated include PCM/FM (ARTM Tier 0 format), Sub-Carrier FM, PM,  BPSK, QPSK, SOQPSK (ARTM Tier 1 format), OQPSK, AQPSK and Multi-H CPM (ARTM Tier 2 format). The digital demodulation includes a bit synchronizer as part of the demodulation so the output is clock and data. Data rates are from 5 kbps to 20 Mbps. Multi-function decom is a standard feature in Lumistar IF Receivers.
