SRP8000 SERIES VHF/UHF PORTABLE RADIO SECTION 3 - TECHNICAL DESCRIPTION INTRODUCTION The SRP8000 Series is a range of advanced portable radios using the latest modern technology to achieve a very high performance in a small size. Internally the radio consists of: (a) Radio PCB A multi-layer assembly with components mounted both sides. (b) MMI PCB Man-Machine-Interface containing the keyboard and display.
POWER SUPPLIES AND ON/OFF CONTROL The main power supply for the radio is the 7,2V battery which is connected directly to the PCB via the battery contacts on the rear of the radio. The power supply has five separate regulators supplying power to the following blocks (see Figure 3.2): VCO PSU +5,6V Frequency generation. RF PSU +5V Transmitter and Receiver and switched supply to Tx and Rx. AF PSU +5,2V Audio and MMI. Control PSU +5V Supply, reference, reset to control and baseband.

RECEIVER Antenna Filter Figure 3.3 on page 3.5 is a block diagram of the receiver and the circuit diagram is shown in Figure 6.8. The antenna low pass filter (L104 to RX_ANT on Figure 6.9) isolates the receiver input during transmissions (D100 forward biased) whilst maintaining a low loss connection from the antenna in the receive state. First Tracking Filter The first tracking band-pass filter limits the unwanted signals that can enter the receive path.

TRANSMITTER The transmitter block diagram is shown Figure 3.4 and the circuit diagram in Figure 6.9. The transmitter consists of a PA module taking its input from the frequency generation block, and feeding an antenna filter and switch. The transmit power is set by processor control of a DAC in the baseband chip IC701. Feedback is not provided to the processor. The processor monitors the battery voltage and the PA temperature, adjusting the transmitter output accordingly.
LOOP_FILTER and VCAP_BIAS, are compared and the difference between them determines the VCO frequency. Oscillator tuning is by varicap diodes D402 to D405 (receive oscillator) and D407 to D411 (transmit oscillator). Separate wideband VCOs (Rx first local oscillator - TR409, and Tx oscillator - TR413), but a common buffer amplifier (TR410, TR414) are used on all bands. Switching between the receiver LO and the transmitter oscillator is achieved by TR415 and TR412.
The synthesizer, IC401, contains two synthesizer circuits. The second circuit is used for the generation of the receiver second local oscillator (output control signal AUX_CP). This removes the need for the alignment of this oscillator because the frequency is locked to the TCXO and allows its frequency to be varied to avoid potential interference. The second local oscillator is switched off during transmissions. The second local oscillator frequency is applied to the synthesizer as AUX_LO2. 3.
CONTROL PROCESSOR SYSTEM The heart of the control processor system consists of the following: (3) (4) (5) (6) H8/3002 Processor (IC600) 32KByte Static RAM (IC601) 512KByte Flash EPROM (IC602) MAX512CSD Triple 10-bit DAC (IC605). The processor controls and monitors the radio functions by a variety of types of digital and analogue interfaces.
The analogue control interfaces are as follows: (1) (2) The processor generates and controls various analogue voltages for receiver and transmitter purposes. IC605 is a triple 10-bit DAC which the processor controls via a 3-wire serial bus. Two of the DAC outputs are used for receiver front-end tuning (RX_TUNE1, RX_TUNE3) and the third for TCXO XL400 frequency trimming. The processor has two pulse width modulator (PWM) outputs which are used as additional analogue control voltages.
Signalling generation is described in the following section. GC11 GC2 F1 F5 F8 EXTERNAL SPEAKER RXOUT1 GC7 + RXIN GC10 INTERNAL SPEAKER RXOUT2 ALERT TONE GENERATOR SELCALL DETECT TXS FFSK DETECT RXDAT RXCLK CD CTCSS DETECT SUB_IO Figure 3.
Signalling Facilities The baseband chip has facilities for CTCSS, SELCALL, DTMF and FFSK signalling. The way in which these signalling modes are controlled and how to they relate to the receive and transmit audio paths is described in the following sections. Figure 3.8 is referred to for receive signalling and Figure 3.9 for transmit signalling. - CTCSS The baseband chip has a CTCSS encoder which is programmed by the processor with the appropriate frequency via the IIC serial bus lines SCL and SDA.

- EXT_LSA, EXT_LSB The bridged audio loudspeaker outputs are capable of delivering 500mW into a 16Ω load. - MIC1 The combined accessory detect and audio input line MIC1 allows the radio to detect what type of ancillary is connected and the ancillary status (such as key presses). Each ancillary has a ‘type’ resistor that sets up a unique voltage on this accessory detect line which is monitored by the comparator formed by IC801_A and its associated components.
(1) (2) (3) The KEY_DET3 voltage generated by the different keys is as follows: If the PTT is pressed, KEY_DET3 voltage will still be at 0V If SIDE_KEY1 or SIDE_KEY2 is pressed, each side key generates a unique KEY_DET3 voltage by virtue of resistors in series with each key (R12, R11, R81) in combination with R15 If the ALARM key is pressed, analogue switch IC3 forces KEY_DET3 voltage to the same voltage as the AF_PSU. The MMI keypad keys generate unique KEY_DET3 voltages.
Four function keys are located below the display: Legend Function M Activate menu – Scroll down through channels (or menu, if active) + Scroll up through channels (or menu, if active) OK Confirm choice or action (ie. Enter). The SRP8030 has 12 additional keys (supported by the daughter board) arranged as a DTMF keypad. – M + OK 1 2 3 4 5 6 7 8 9 * 0 # Figure 3.
TRICKLE CHARGER The trickle charger uses a positive input on the RxD pin of the smart interface to power a current limited source feeding the battery, limiting the current to approximately 130mA. The charger is enabled by the thermistor in the battery pack, so it is inhibited if a battery pack is not fitted (this is necessary to prevent a voltage at the battery connector which could damage the radio when no battery is present).
SRP8000 SERIES VHF/UHF PORTABLE RADIO SECTION 4 - SERVICING CAUTION Metal Oxide Semiconductors (MOS) are used in this equipment; therefore the following predictions should be strictly observed, otherwise the devices may become damaged. (4) (5) (6) (7) (8) Device leads should always be in contact with a conductive material to avoid the build-up of static charges. Soldering iron tips, tools and metal parts of test equipment used in servicing must be grounded.
Remove the Metal Frame Assembly (1) (2) (3) (Refer to Figure 4.2) Use a small, flat bladed screwdriver to release the cast metal frame assembly from the bottom of the front casing. This action releases the radio PCB from the MMI PCB. Gently ease the frame assembly out of the front casing taking care not to damage the two flexi-circuits (lift the bottom of the frame so that it just clears the plastic casing, then gently slide the frame away from the top of the casing until it is released from the casing).
(2) (1) (1) (1) (1) (1) (1) (1) Figure 4.3 Removing the Metal Screen Remove the Radio PCB (1) (2) (Refer to Figure 4.4) Release the remaining flexi-circuit from the radio PCB as follows: (a) Slide out the locking drawer of the PCB connector, SK6, (on the radio PCB). Use a very small flat bladed screwdriver. (b) Remove the flexi-circuit from the connector, SK6. The PCB is held in place by a leaf spring near the top of the unit (on the hidden side of the PCB).
Remove the Speaker and Microphone (1) (2) (Refer to Figure 4.5) Remove the speaker retaining clip. Lift the speaker / microphone assembly away from the front casing taking care not to damage the flexi-circuit. (2) (1) Figure 4.5 Removing the Speaker / Microphone Assembly Remove the MMI PCB (1) (2) (Refer to Figure 4.6) The MMI PCB is held in place by four plastic lugs on the front casing.
RE-ASSEMBLY (1) (2) (3) (4) (5) Re-assembly is the reverse of dis-assembly. However: Examine the various seals before re-assembly and replace with new items if necessary. Slight outward deflection of the case walls will ease re-assembly of the MMI PCB behind the retaining lugs. Care must be taken when reconnecting the flexi-circuits to ensure that they are correctly aligned before pressing home the locking drawers on the connectors.
Test Equipment The following is a list of test equipment recommended for carrying out functional tests, setting-up and fault location. Alternative types may be used provided that they are known to have at least equivalent parameters and that corrections are made for any differences in parameters.
