Receiver Description The RF63 is set to receive mode when MCParam_Chip_mode = 011. 3.4.1. Architecture The RF63 receiver employs a super-heterodyne architecture. Here, the first IF is 1/9 th of the RF frequency (approximately 100MHz). The second down-conversion down-converts the I and Q signals to base band in the case of the FSK receiver (Zero IF) and to a low-IF (IF2) for the OOK receiver. After the second down-conversion stage, the received signal is channel-select filtered and amplified to a level adequate for demodulation. Both FSK and OOK demodulation are available. Finally, an optional Bit Synchronizer (BitSync) is provided, to be supply a synchronous clock and data stream to a companion uC in Continuous mode, |
