CIRCUIT DESCRIPTION 4.1 GENERAL 4.1.1 INTRODUCTION The DM-3473 consists of a low dropout regulator power supply, frequency synthesizer and VCO (voltage controlled oscillator), 2 watt RF power amplifier, and dual down conversion FM receiver. A block diagram of the transceiver is located in Figure 4-1 and shows the four major sections of the unit. The VCO is enclosed by a metal shield and soldered directly to the printed circuit board (PCB). The VCO unit is not field serviceable. The transmitter is also covered by a metal shield to prevent radiation of RF power causing interference. The 3473 comes standard with a reference oscillator stability of + 1.5 PPM over the entire operating temperature range. 4.2 POWER SUPPLY CIRCUIT DESCRIPTION Main DC power is delivered to the transceiver on pin 5 of the user interface connector (J201). This pin requires a regulated power supply voltage between 6 and 9 VDC. The voltage on this pin powers the on board low drop out regulator U130. The regulator provides constant 5.5 VDC to all of the relevant sections of the transceiver such as the VCO/Synthesizer, Receiver, and Regulator sections of the transmitter. Pins 1 and 2 provide the ground connection of the transceiver. Pins 3 and 4 of J201 are the main power supply to the RF power amplifier. This voltage is set between 6 and 9 VDC with 7.2 VDC being the nominal voltage to guarantee 2 watts +\-0.4 watts of RF power at the antenna connector. All three pins (3,4,and 5) can be tied together on a customer interface board if the maximum voltage limits are always between 6-9 VDC. The transmit and receive enable pins (pins 6 and 7) of J201 are a logic voltage input to turn on the transmitter or receiver. The necessary voltage is between 4.5 and 13 VDC for the enable mode. Refer to the programming section 3 for the implementation of the transmit and receive enable pins. The DM-3473 is equipped with a sleep mode pin for implementing current saving features by the customer when a transceiver requires a standby mode. Pin 8 requires a logic level >2.0 VDC to enable the transceiver, this voltage must always be high when the transceiver is in operation. Pin 8 can be grounded to put the radio to sleep. The transceiver will draw less than one milliampere in sleep mode. 4.3 SYNTHESIZER/VCO/TX MODULATION The VCO is an oscillator which can be controlled by an input voltage to oscillate at a desired frequency. The VCO in the 3473 serves either the receiver or the transmitter dependent on the desired operation. The frequency of the VCO for receive mode is 86.85 MHz above the desired receive frequency. For the transmitter the VCO produces the signal corresponding to the desired transmit frequency. The DC voltage controlling the oscillator frequency is generated by synthesizer IC U811. The VCO control voltage can be measured at test point TP831 on the PCB. When the VCO is locked (>3.5 Vdc on pin 11 of J201) TP831 will measure between 0.5 and 5.00 VDC, dependent on the frequency of operation. An unlocked condition (indicated on pin 11 of J201) is less than 1.5 VDC. The synthesizer determines the lock state of the radio by comparing the scaled VCO frequency to the scaled reference oscillator TCXO of 14.4 MHz. The VCO is a Colpitts oscillator formed by Q962 along with several capacitors, varactor diodes, and a ceramic resonator. The DC bias to the VCO is provided by transistor Q901 and forms a capacitance multiplier which delivers filtered, noise free supply voltage to the oscillator circuitry. The VCO is followed by gain stages which amplify the signal to approximately 0 dBm and then divide the signal using a splitter and sending it to the receiver or transmitter. The VCO is capable of oscillating between 403-434 MHz or 450-480 MHz in transmit and 489.85-520.85 MHz or 536.85-566.85 MHz in receive. The course frequency shift in the VCO between receive and transmit is accomplished by shifting in a capacitor to the tank of the oscillator. Pin 7 of J201 (receive enable) performs this function. When transmitting, the receive enable is forced low and a pin diode is turned on by a digital transistor connected to pin 7 which switches capacitance into the oscillator circuit. The reverse happens when returning to receive mode. Refer to section 3 for receive to transmit and transmit to receive load sequences. There are two parts to the transceiver modulation circuitry. With the placement of the VCO control line voltage low pass filter at approximately 400 Hz, it is necessary to modulate both the VCO and the TCXO. A loop response of 400 Hz is necessary to accomplish the fast lock times of the 3473. If only the VCO were modulated to transmit data, any baseband frequency component below 400 Hz would not be modulated onto the transmit carrier. To accomplish this the transceiver was designed to modulate both the VCO and TCXO, thus creating two parts to the modulation circuit and modulation capability from below 50 Hz up to 5000 Hz. It is important to note that modulation sensitivity adjustment and modulation deviation limiting are to be supplied in the customer interface equipment, and are required by most regulatory agencies, such as the Federal Communications Commission (FCC) in the United States. The modulation flatness adjustment (R825) balances the sensitivity of the VCO vs. the TCXO. The radio is set to best modulation flatness in the center of the RF band (418.5 MHz or 465 MHz) when the unit leaves the Dataradio factory. The modulation flatness becomes uneven when nearing the band edges due to changing sensitivity of the TCXO and VCO across a wide range of RF frequencies. If optimal modulation flatness is desired across the whole RF band of 450-480 or 403-434 MHz, the unit is equipped with an external flatness adjust. Pin 9 of J201 allows the implementation of an analog voltage between 0 and 5 VDC to obtain flat modulation. Linear interpolation of this voltage between the RF band edges will insure flat modulation everywhere in the band. If…

ALIGNMENT PROCEDURE AND PERFORMANCE TESTS 6.1 GENERAL Receiver or transmitter alignment may be necessary if repairs are made that could affect tuning. Alignment points diagrams are located in Figure 6-3 or component layouts are located in Section 8. Fabricate test cables by referring to Section 2.2 Interfacing with Data Equipment. This cable should include power and ground, a transmit keying switch that applies 5.5 VDC to the Rx and Tx Enable, data input and data output. The test setup must apply the various supply voltages and load the synthesizer with channel information. 6.2 ALIGNMENT PROCEDURE 6.2.1 VCTCXO SETUP (Y801) 1. Apply 7.2 Vdc +\-0.1 Vdc to pins 3, 4, and 5. 2. Verify 2.5 Vdc +\- 0.05 Vdc is on pin 10. 3.

Connect the test setup shown in Figure 6-1. A DC ammeter capable of measuring up to 2.0 A should be installed in the supply line. 2. Load the synthesizer with the desired channel frequency. 3. Set the IDSS of the final by shorting TP601. To Ground R521, turn counter-clockwise for minimum transmit current. Note the current and adjust R521 for 200 mA more current. 4. Key the transmitter and make sure that pins 3, 4, and 5 on the RF board are 7.2V. (Do not transmit for extended periods.) 5. Adjust C552 for 100 milliwatts output power.
