1 1.1 GENERAL Introduction The OS-3A/H Synthesizer Module produces a low distortion, high stability, FM modulated (FM transmitter) or unmodulated (receiver LO, AM transmitter) RF signal covering the frequency bands of 29 - 50 MHz, 118 - 159.4 MHz, 118 - 174 MHz and 406 - 470 MHz. It achieves ±1 ppm frequency stability from -40°C to +60°C with its own internal reference, or it can be slaved to an external 10/9.6 MHz reference signal of desired stability.

1.4 Printed Circuit Board Numbering Convention To ease troubleshooting and maintenance procedures, Daniels Electronics Limited has adopted a printed circuit board (PCB) numbering convention in which the last two digits of the circuit board number represent the circuit board version. For example: • • PCB number 43-912010 indicates circuit board version 1.0; PCB number 50002-02 indicates circuit board version 2.0.

2 2.1 THEORY OF OPERATION 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. For receiver applications, the synthesizer is always operating with the enable line P2-4 permanently connected to +9.

(Analog Board) and jumper JU2 (AM Analog Board only) installed. 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 ± 3 dB. A sinusoidal signal shape is required for an external reference source.
PAGE 11
2.2.2 29 - 71.4 MHz Analog Board Circuitry Refer to the "OS(R/T)-3H 29 - 71.4 MHz Analog Board Schematic Diagram" located in section 4 page 3 of this manual. Field effect transistor Q5 provides a VHF negative resistance amplifier/oscillator that is tuned on frequency by the combination of resonator L5 and a total capacitive reactance presented across L5 through capacitors C62, C63, C64, C23 (Select), variable capacitor C24, and varactor diodes D1 and D2.
PAGE 12
diodes D1 and D2. Coarse frequency adjustment is provided by varactor diodes D6, D7. Select capacitor values C40 or C23 are chosen to position the operating frequency in one of two bands; 118 - 138 MHz, and 139.4 - 159.4.MHz. Varactor diodes D1 and D2 provide fine oscillator frequency control. PLL voltage feedback control from the output of the lowpass loop filter controls the VCO frequency through the reverse biasing of diodes D1 and D2. The PLL control voltage can range from ≈ +1.0 Vdc to +4.
PAGE 13
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. The loop filter response is optimized for switching time, noise, and modulation requirements specific to each sub-band within the 128 - 174 MHz frequency range.
PAGE 14
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.
PAGE 15
subtracted from the synthesizer operating frequency in order to determine the actual receive frequency. Refer to the channel designation table documentation provided with the transmitter or receiver modules for simplified channel number and frequency information. 2.4.2 Frequency Select Handle Frequency Control For operation in this mode the external channel select must be set to channel #16.
PAGE 16
2.6 5.0/6.25 kHz Channelization. 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. The selected channel number is 0988. The synthesizer output frequency is: ((988 x 5 kHz) + 128 MHz) = 132.
PAGE 17
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. The synthesizer output frequency is: ((1978 x 12.5 kHz) + 406 MHz) = 430.

3 3.1 SYNTHESIZER ALIGNMENT 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. Receiver balanced audio (600 Ω) is available at pins B26 and Z26. 3.

unstable or spurious RF output signal. The "Unlocked" red LED will also be illuminated when the PLL is unlocked. 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).
