    Chapter 2 THEORY OF OPERATION Introduction This Chapter provides a detailed theory of operation for the UHF circuits in the radio. Details of the theory of operation and trouble shooting for the the associated Controller circuits are included in this Section of the manual.

  • Page 10: Receiver Back End

    THEORY OF OPERATION Receiver Back End The IF signal from the crystal filter enters the IF amplifier which provides 20 dB of gain and feeds the IF IC at pin 1. The first IF signal at 44.85 MHz mixes with the second local oscillator (LO) at 44.395 MHz to produce the second IF at 455 kHz.

  • Page 11: Power Controlled Driver Stage

    UHF Transmitter Power Amplifier (403-440 MHz) PA.Op-amp U103-3 monitors the drain current of U101 via resistor R122 and adjusts the bias voltage of U101. In receive mode, the DC voltage from RX_EN line turns on Q101, which in turn switches off the biasing voltage to U101.

  • Page 12: Harmonic Filter

    THEORY OF OPERATION Harmonic Filter Inductors L111, L113 and L128 along with capacitors C1011, C1023, C1020, C1016, C1025 and C1026 form a low-pass filter to attenuate harmonic energy coming from the transmitter. Resistor R150 along with L130 drains any electrostatic charges that might otherwise build up on the antenna. The harmonic filter also prevents high level RF signals above the receiver passband from reaching the receiver circuits to improve spurious response rejection.

  • Page 13: Fractional-N Synthesizer

    UHF (403-440MHz) Frequency Synthesizer parameters (four characterize the inverse Bechmann voltage curve and one for frequency accuracy of the reference oscillator at 25 degrees C). This algorithm is implemented by the LVFRAC-N (U200) at the power up of the radio. TCXO Y200, along with its corresponding circuitry R204, R205, R210, and C2053, are not placed as the temperature compensated crystal proved to be reliable.

    THEORY OF OPERATION Voltage Controlled Oscillator (VCO) The Voltage Controlled Oscillator (VCO) consists of the VCO/Buffer IC (VCOBIC, U201), the TX and RX tank circuits, the external RX buffer stages, and the modulation circuitry. AUX3 (U200 Pin 2) U200 Pin 32 Prescaler Out TRB IN Pin 20...

  • Page 15: Synthesizer Operation

    UHF (403-440MHz) Frequency Synthesizer Synthesizer Operation The synthesizer consists of a low voltage FRAC-N IC (LVFRAC-N), reference oscillator, charge pump circuits, loop filter circuit, and DC supply. The output signal (PRESC_OUT) of the VCOBIC (U201, pin 12) is fed to the PREIN, pin 32 of U200 via a low pass filter which attenuates harmonics and provides a correct input level to the LVFRAC-N in order to close the synthesizer loop.

  • Page 16: Controller Theory Of Operation

    THEORY OF OPERATION Controller Theory of Operation This section provides a detailed theory of operation for the radio and its components. The main radio is a single-board design, consisting of the transmitter, receiver, and controller circuits. A control head is connected by an extension cable.

  • Page 18: Protection Devices

    2-10 THEORY OF OPERATION Voltage regulator U503 provides 5V for the RF circuits. Input and output capacitors are used to reduce the high frequency noise and provide proper operation during battery transients. VSTBY is used only for CM360 5-tone radios. The voltage VSTBY, which is derived directly from the supply voltage by components R5103 and VR502, is used to buffer the internal RAM.

  • Page 19: Microprocessor Clock Synthesiser

    Controller Theory of Operation 2-11 5.3.3 Emergency Mode The emergency switch (P1 pin 9), when engaged, grounds the base of Q506 via EMERGENCY _ACCES_CONN. This switches Q506 to off and consequently resistor R5020 pulls the collector of Q506 and the base of Q506 to levels above 2 volts. Transistor Q502 switches on and pulls U501 pin2 to ground level, thus turning ON the radio.

  • Page 20: Serial Peripheral Interface (Spi)

    2-12 THEORY OF OPERATION Serial Peripheral Interface (SPI) The µP communicates to many of the IC’s through its SPI port. This port consists of SPI TRANSMIT DATA (MOSI) (U403-pin100), SPI RECEIVE DATA (MISO) (U403-pin 99), SPI CLK (U0403-pin1) and chip select lines going to the various IC’s, connected on the SPI PORT (BUS). This BUS is a synchronous bus, in that the timing clock signal CLK is sent while SPI data (SPI TRANSMIT DATA or SPI RECEIVE DATA) is sent.

  • Page 21: Normal Microprocessor Operation

    Controller Theory of Operation 2-13 Normal Microprocessor Operation For this radio, the µP is configured to operate in one of two modes, expanded and bootstrap. In expanded mode the µP uses external memory devices to operate, whereas in bootstrap operation the µP uses only its internal memory.

  • Page 22: Static Random Access Memory (Sram)

    2-14 THEORY OF OPERATION Static Random Access Memory (SRAM) The SRAM (U402) contains temporary radio calculations or parameters that can change very frequently, and which are generated and stored by the software during its normal operation. The information is lost when the radio is turned off. The device allows an unlimited number of write cycles.

To generate an ISW, the µP first programs the ASFIC CMP (U504) to the proper filter and gain settings.

    Receive Signalling Circuits 2-21 Handset Audio Certain handheld accessories have a speaker within them which require a different voltage level than that provided by U502. For these devices HANDSET AUDIO is available at control head connector J2 pin18. The received audio from the output of the ASFIC CMP’s digital volume attenuator is routed to U505 pin 2 where it is amplified.

    2-22 THEORY OF OPERATION The low speed limited data output (PL, DPL, and trunking LS) appears at U504-pin18, where it connects to the µP U403-pin 80. The low speed data is read by the µP at twice the frequency of the sampling waveform; a latch configuration in the ASFIC CMP stores one bit every clock cycle.
