    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 Motorolas MOSAIC 1.5 process, these receivers offerlow 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 standalone VHF receivers or as the lower

    IF of a triple conversion system. Applications include cordless telephones,

    short range data links, walkietalkies, low cost land mobile, amateur radio

    receivers, baby monitors and scanners.

    TEST CIRCUIT INFORMATION

    Although the MC13136 can be operated with a ceramic

    discriminator, the recovered audio measurements for both

    the MC13135 and MC13136 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. On the

    MC13136, an external capacitor between Pins 13 and 14 can

    be used with a quad coil for slightly higher recovered audio.

    See Figures 10 through 13 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 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 MC13135/13136 are complete dual conversion

    receivers. They include two local oscillators, two mixers, a

    limiting IF amplifier and detector, and an op amp. Both

    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.

    VCCTwo separate VCC 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 crystalcontrolled or VCO controlled with the

    onboard varactor and external PLL. The first LO transistor is

    internally biased, but the emitter is pinnedout 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

    singleended 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 pinnedout 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 requireabout 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 MHzfirst IF. It is designed for use with a ceramic filter, with an

    output impedance of 330 . 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 k. The second mixer

    input impedance is approximately 4.0 k; it requires an

    external 360 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 MC13135 is designed for use with an LC quadrature

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

    ceramic discriminator. The MC13136 was designed to use a

    ceramic discriminator, but can also be run with an LC quad

    coil, as mentioned in the Test Circuit Information section. The

    data shown in Figures 12 and 13 was taken using a muRata

    CDB455C34 ceramic discriminator which has been specially

    matched to the MC13136. Both the choice of discriminators

    and the external matching circuit will affect the distortion and

    recovered audio.

    RSSI/Op Amp

    The Received Signal Strength Indicator (RSSI) on theMC13135/13136 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

    MC13136, the op amp on board is connected to the output to

    provide a voltage buffered RSSI. On the MC13135, the op

    amp is not connected internally and can be used for the RSSI

    or as a data slicer (see Figure 17c).
