MC13136

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.
