www.lansdale.comPage 1 of 11 Issue 0 ML13135 FM Communications Receiver; Dual Conversion Narrowband FM Receiver Legacy Device: Motorola MC13135 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. OPERATING FEATURES

ML13135 Test Circuit The recovered audio measurements for the ML13135 are made with an LC quadrature detector. The typical recovered audio will depend on the external circuit; either the Q of the quad coil, or the RC matching network for the ceramic dis- criminator. See Figures 10 and 11 for additional information. Since adding a matching circuit to the RF input increases the signal level to the mixer, the third order intercept (TOI) point is better with an unmatched input (50 Ωfrom Pin 21 to Pin 22). T ypical values for both have been included in the Electrical Characterization Table. TOI measurements were taken at the pins with a high impedance probe/spectrum ana- lyzer system. The first mixer input impedance was measured at the pin with a network analyzer. TEST CIRCUIT INFORMATION
