Legacy Device: Motorola MC13135
ML13135
FM Communications
Receiver; Dual Conversion
Narrowband FM Receiver
The ML13135 is 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. These receivers offer low noise, high gain and
stability over a wide operating voltage range, and Lansdale is pleased
to continue to offer them.
The ML13135 includes a Colpitts oscillator, VCO tuning diode, low
noise first and second mixer and LO, high gain limiting IF, and RSSI.
The ML13135 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.
This device can be used as a stand–alone VHF receiver 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.
