  • Page 9: Theory Of Operation

    THEORY OF OPERATION 2.1 Internal Power and Control (Digital Board) Refer to "OS(R/T)-3(A/H) Digital Board Schematic Diagram" in section 4 page 19. The synthesizer operates from +9.5 Vdc applied to connector pin P1-2. Total current drain is approximately 160 mA (65 ma for AM). Power Down control (P2-4) controls the +5.0 Vdc microcontroller regulator U2 through power MOSFET switch U1.

The external reference source may be 9.6 MHz or 10.0 MHz through selection of jumper JU2 (Digital Board); install jumper JU2 (Digital Board) for 10.0 MHz reference selection. If an external signal is used for the reference source, it must be of low phase noise, high stability, with a level of 0 dBm ±...

    C53, C57, C58, C59, L11, and L13. The six pole output filter provides a 50 MHz (OST-3H035, OST-3H045 TX) or 80 MHz (OSR-3H061 RX) cutoff frequency which reduces harmonic output to acceptable levels. SMB connector J2 provides interconnection to the companion transmitter or receiver with an output level of ≈...

    division ratio, established by the resistive dividers R21 and R22, allows low deviation (less than 5 kHz) direct frequency modulation of the VCO output signal. The PLL lowpass filter is formed from select component values C37, C38, C39, C45, R32, and R36.

  • Page 14: Synthesizer Digital Circuitry (Digital Board)

    2.3 Synthesizer Digital Circuitry (Digital Board) Refer to the "OS(R/T)-3(A/H) Digital Board Schematic Diagram" on page 4-19. Microcontroller U4 provides control of the synthesizer module. It communicates with synthesizer IC U10, monitors the synthesizer lock detect, manages PTT input/output, and determines the operating frequency from either four rotary BCD switches or four externally driven channel select lines.

The operating frequency is determined as follows for Synthesizers having 5.0/6.25 kHz channel increment capability; • for BCD switch settings (in the range of 0000 to 4999 , multiply the switch setting by 5.0 kHz and add it to the synthesizer base frequency. Example: An OST-3H141 synthesizer has a base frequency of 128 MHz.

    2.8 12.5 kHz Channelization. The operating frequency is determined as follows for Synthesizers having 12.5 kHz channel increment capability; • Multiply the BCD switch setting by 12.5 kHz and add it to the synthesizer base frequency. Example: An OST-3H440 synthesizer has a base frequency of 406 MHz. The selected channel number is 1978.

  • Page 19: Synthesizer Alignment

    SYNTHESIZER ALIGNMENT 3.1 General OS(R/T)-3(A/H) enhanced synthesizer alignment is simplified by using a Type 84 subrack and RF extender card/cable to provide receiver or transmitter power and signal interconnection. Alternatively, +9.5 Vdc may be applied directly to a receiver or transmitter module through positive connection to pins B6 / Z6, and negative connection to pins B30 / Z30 / B32 / Z32.

  • Page 21: Synthesizer Removal And Installation

    3.5.3 Synthesizer Removal and Installation The synthesizer module is fastened to the main board (MT-3 Receiver IF/Audio Board or MT-3 Transmitter Main board) with a single counter sunk Phillips machine screw accessible from the top cover. Remove this screw to remove the synthesizer module. Using a plastic coated lifting tool, such as a small screwdriver with the tip covered in heat shrink material, gently lift the synthesizer module from the main circuit board by applying pressure in a rotating fashion about four corners of the synthesizer module.

Check that the requested channel number is within the frequency range of the particular synthesizer model. An unlocked condition may be rectified by adjusting the VCO tuning elements as described in the following procedures (no adjustment requires for the multichannel AM Synthesizers).
