MC28332 Single Chip VHF Narrowband FM Transmitter Application Circuit


Posted on Feb 4, 2014

Crystal X1 is fundamental mode, calibrated for parallel resonance with a 32 pF load. The final output frequency is generated by frequency multiplication within the MC2833 IC. The RF output Buffer (Pin 14) and Q2 Transistor are used as a frequency tripler and doubler, respectively, in the 76 and 144. 6 MHz Transmitters
