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.

TEST CIRCUIT INFORMATION 

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 discriminator. 

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 Ω from Pin 21 to Pin 

22). Typical values for both have been included in the 

Electrical Characterization Table. TOI measurements were 

taken at the pins with a high impedance probe/spectrum analyzer 

system. The first mixer input impedance was measured at 

the pin with a network analyzer.

CIRCUIT DESCRIPTION 

The ML13135 is a complete dual conversion receiver. This 

includes two local oscillators, two mixers, a limiting IF amplifier 

and detector, and an op amp. It will provide a voltage 

buffered RSSI with 70 dB of usable range, isolated tuning 

diode and buffered LO output for PLL operation, and a separate 

VCC pin for the first mixer and LO. Improvements have 

been made in the temperature performance of both the recovered 

audio and the RSSI. 

VCC 

Two separate V CC lines enable the first LO and mixer to 

continue running while the rest of the circuit is powered down. 

They also isolate the RF from the rest of the internal circuit. 

Local Oscillators 

The local oscillators are grounded collector Colpitts, which 

can be easily crystal–controlled or VCO controlled with the 

on–board varactor and external PLL. The first LO transistor is 

internally biased, but the emitter is pinned–out and IQ can be 

increased for high frequency or VCO operation. The collector 

is not pinned out, so for crystal operation, the LO is generally 

limited to 3rd overtone crystal frequencies; typically around 60 

MHz. For higher frequency operation, the LO can be provided 

externally as shown in Figure 16. 

Buffer 

An amplifier on the 1st LO output converts the single–ended 

LO output to a differential signal to drive the mixer. Capacitive 

coupling between the LO and the amplifier minimizes the 

effects of the change in oscillator current on the mixer. 

Buffered LO output is pinned–out at Pin 3 for use with a PLL, 

with a typical output voltage of 320 mVpp at VCC= 4.0 V and 

with a 5.1 k resistor from Pin 3 to ground. As seen in Figure 

14, the buffered LO output varies with the supply voltage and 

a smaller external resistor may be needed for low voltage operation. 

The LO buffer operates up to 60 MHz, typically. Above 

60 MHz, the output at Pin 3 rolls off at approximately 6.0 dB 

per octave. Since most PLLs require about 200 mVpp drive, an 

external amplifier may be required. 

Mixers 

The first and second mixer are of similar design. Both are 

double balanced to suppress the LO and input frequencies to 

give only the sum and difference frequencies out. This configuration 

typically provides 40 to 60 dB of LO suppression. New 

design techniques provide improved mixer linearity and third 

order intercept without increased noise. The gain on the output 

of the 1st mixer starts to roll off at about 20 MHz, so this 

receiver could be used with a 21 MHz first IF. It is designed 

for use with a ceramic filter, with an output impedance of 330 

Ω. A series resistor can be used to raise the impedance for use 

with a crystal filter, which typically has an input impedance of 

4.0 kΩ. The second mixer input impedance is approximately 

4.0 kΩ; it requires an external 360 Ω parallel resistor for use 

with a standard ceramic filter. 

Limiting IF Amplifier and Detector 

The limiter has approximately 110 dB of gain, which starts 

rolling off at 2.0 MHz. Although not designed for wideband 

operation, the bandwidth of the audio frequency amplifier has 

been widened to 50 kHz, which gives less phase shift and 

enables the receiver to run at higher data rates. However, care 

should be taken not to exceed the bandwidth allowed by local 

regulations. 

The ML13135 is designed for use with an LC quadrature 

detector, and does not have sufficient drive to be used with a 

ceramic discriminator. The discriminators and the external 

matching circuit will affect the distortion and recovered audio. 

RSSI/Op Amp 

The Received Signal Strength Indicator (RSSI) on the 

ML13135 has about 70 dB of range. The resistor needed to 

translate the RSSI current to a voltage output has been included 

on the internal circuit, which gives it a tighter tolerance. A 

temperature compensated reference current also improves the 

RSSI accuracy over temperature. On the ML13135, the op amp 

is not connected internally and can be used for the RSSI or as 

a data slicer (see Figure 17c).
