The MC13135/MC13136 are the second generation of single chip, dual
conversion FM communications receivers developed by Motorola. Major
improvements in signal handling, RSSI and first oscillator operation have
been made. In addition, recovered audio distortion and audio drive have
improved. Using Motorola’s MOSAIC 1.5 process, these receivers offer
low noise, high gain and stability over a wide operating voltage range.
Both the MC13135 and MC13136 include a Colpitts oscillator, VCO tuning
diode, low noise first and second mixer and LO, high gain limiting IF, and
RSSI. The MC13135 is designed for use with an LC quadrature detector and
has an uncommitted op amp that can be used either for an RSSI buffer or as
a data comparator. The MC13136 can be used with either a ceramic
discriminator or an LC quad coil and the op amp is internally connected for a
voltage buffered RSSI output.

These devices can be used as stand–alone VHF receivers or as the lower
IF of a triple conversion system. Applications include cordless telephones,
short range data links, walkie–talkies, low cost land mobile, amateur radio
receivers, baby monitors and scanners.
