MCUB5R - ENGINEERING REPORT-Annex APage 1 of 14 04\16\99 156-90002-100 Dataradio  FCC submission Annex A:Operational Description of Circuitry RULE PART NUMBER:2.1033 (c)(10) 1PURPOSE This report has been prepared to support the application for FCC Certification Per Code Of Federal Regulations, Title 47, Parts 2 And 90 for the MCUB5R radio-modem comprised of the JDT Model 242- 3412-xxx Transceiver and Dataradio 210-3315-xxx Modem. The report presents necessary information concerning electrical circuit description, measured performance and physical construction and configuration. Also parts 4 and 5 present active circuit devices functions for Transceiver and, accordingly, for Modem. 2.0DL-3412 TRANSCEIVER The main subassemblies of this transceiver are the RF board, VCO board, TCXO and modem assembly. A block diagram of the transceiver is located in Figure 2. The VCO board is enclosed by a metal shield and soldered directly to the RF board. The VCO is not serviceable. The DL3412 is available with a reference oscillator stability of ±1.5 PPM. The 17.5 MHz TCXO (Temperature Compensated Crystal Oscillator) is soldered directly to the RF board. The TCXO is not serviceable. 2.1SYNTHESIZER As stated previously, the synthesized output signal is produced by a VCO (voltage controlled oscillator). The VCO frequency is controlled by a DC voltage produced by the phase detector in U801. The phase detector senses the phase and frequency of the two input signals and causes the VCO control voltage to increase or decrease if they are not the same. The VCO is then "locked" on frequency. Programming of the synthesizer provides the data necessary for the internal prescaler and counters. One input signal is the reference frequency. This frequency is produced by the 17.5 MHz reference oscillator (TCXO). The other input signal is the VCO frequency. VOLTAGE-CONTROLLED OSCILLATOR Oscillator (Q850) The VCO is formed by Q850, several capacitors and varactor diodes, and ceramic resonator Z850. It oscillates at the transmit frequency in transmit mode and first injection frequency in the receive mode ( 403-512 MHz in transmit and 455.95-564.95 MHz in receive). Biasing of Q850 is provided by R862, R867 and R865. An AC voltage divider formed by C861, C862 and C859 initiates and maintains oscillation and also matches Q850 to the tank circuit ceramic resonator Z850 is grounded at one end to provide shunt inductance to the tank circuit. FREQUENCY CONTROL AND MODULATION The VCO frequency is controlled in part by DC voltage across varactor diodes CR851, CR854, CR855 and CR856. As voltage across a reverse-biased varactor diode increases, its capacitance decreases. Therefore, VCO frequency increases as the control voltage increases. CR851/CR856 and CR854/CR855 are paralleled varactors to divide the capacitance and improve linearity. The varactors CR851/CR854 are MCUB5R - ENGINEERING REPORT-Annex APage 2 of 14 156-90002-100 Dataradio  FCC submission biased at -2.0V so the control line voltage can operate closer to ground. The control line is isolated from tank circuit RF by choke L851/L854. The amount of frequency change produced by CR851/CR854/CR855/CR856 is controlled by series capacitor C859. The -2.0V applied to the VCO is derived from the 17.5 MHz TCXO frequency that is amplified by Q701, rectified by CR701 and filtered by C705, C706, C707 and C708 on the RF board. The VCO frequency is modulated using a similar method. The transmit audio/data signal from J201, pin 6 is applied across varactor diode CR852 which varies the VCO frequency at an audio rate. Series capacitors C856/C870 set the amount of deviation produced along with CR853 and C858. R854 provides a DC ground on the anodes of CR852/CR853, and isolation is provided by R852 and C855. The DC voltage across CR853 provides compensation to keep modulation relatively flat over the entire bandwidth of the VCO. This compensation is required because modulation tends to increase as the VCO frequency gets higher (capacitance of CR854/CR855/CR856/CR851 gets lower). CR853 also balances the modulation signals applied to the VCO and TCXO. The DC voltage applied across CR853 comes from the modulation adjust control R827 on the RF board. R826 applies a DC biasing voltage to CR852. C821 provides DC blocking. RF isolation is provided by C858, R853 and R847. VCO AND REFERENCE OSCILLATOR MODULATION Both the VCO and reference oscillator (TCXO) are modulated in order to achieve the required frequency response. If only the VCO was modulated, the phase detector in U801 would sense the frequency change and increase or decrease the VCO control voltage to counteract the change (especially at the lower audio frequencies). If only the reference oscillator frequency is modulated, the VCO frequency would not change fast enough (especially at the higher audio frequencies). Modulating both VCO and reference oscillators produces a flat audio response. Potentiometer R827 sets the VCO modulation sensitivity so that it is equal to the reference oscillator modulation sensitivity. CASCODE AMPLIFIERS (Q851/Q852) The output signal on the collector of Q850 is coupled by L861/C864 to buffer amplifier Q851/Q852. This is a shared-bias amplifier which provides amplification and also isolation between the VCO and the stages which follow. The signal is direct coupled from the collector of Q852 to the emitter of Q851. The resistors in this circuit provide biasing and stabilization, and C865 and C866 are bypass capacitors. AMPLIFIER (Q853) Amplifier Q853 provides amplification and isolation between the VCO and receiver, and transmitter. C868 provides matching between the amplifiers. Bias for Q853 is provided by R871, R872 and R874. Inductor L856 and capacitor C873 provide impedance matching on the output. VOLTAGE FILTER (Q901) Q901 on the RF board is a capacitance multiplier to provide filtering of the 4.6V supply to the VCO. R901 provides transistor bias and C901 provides the capacitance that is multiplied. If a n…

9. Tune-up procedure Ref: FCC Part 2 paragraph 2. 1033(c)(9) 1. Connect the transceiver to be aligned to a DC power source. A DC current meter capable of measuring at least 2.5 Amps should be connect in line with the DC source. Connect the output of the transceiver through a watt meter and into a 50 ohm dummy load. 2. Load the synthesizer with the center channel frequency. 3. Key the transmitter and make certain that the supply voltage at the RF board is 13.3 VDC. (Do not transmit for extended periods of time. ) 4. Adjust R535 clockwise for 5.0 Watts of output power. 5. Check the power levels on the low and the high frequencies for 5.0 Watts +/- 1 Watt. 4.
