CIRCUIT DESCRIPTION

1. Overview

The KENWOOD model TK-5210(G) is a VHF/FM/P25 Portable transceiver designed to operate in the frequency range of 136 to 174MHz.

The unit consists of a receiver, a transmitter, a phaselocked loop (PLL) frequency synthesizer, a digital control unit, power supply circuit.

2. Frequency Conﬁ guration

The receiver is a double-conversion super heterodyne using first intermediate frequency (IF) of 49.95MHz and second IF of 450kHz. Incoming signals from the antenna are mixed with the local signal from the PLL circuit to produce the ﬁ rst IF of 49.95MHz.

This is then mixed with the 50.4MHz second local signal to produce the 450kHz second IF. This signal is detected to give the demodulated signal in the DSP.

The transmit signal frequency is generated by the PLL VCO, and modulated by the signal from the DSP. It is then ampliﬁ ed and fed to the antenna.

3. Receiver System

3-1. Front-end RF Ampliﬁ er

The signal is passed through an antenna matching coil, where the high-frequency components are amplified by a GaAs FET (Q202). The signals are then fed into band-passﬁ lter that uses varactor diode tuning to reject unwanted signal components, and is fed to the 1st mixer.

3-2. 1st Mixer

The 1st mixer is used the GaAs IC (IC202). The 1st mixer mixes the signal with the 1st local oscillator frequency from the VCO, and converts it to the 1st IF (49.95MHz). The signal then passes through monolithic crystal ﬁ lter (XF201) to remove unnecessary nearby frequency components. The signal from the MCF is used as the 1st IF signal.

3-3. IF Ampliﬁ er

The 1st IF signal is ampliﬁ ed by the IF ampliﬁ er (Q204) and fed into the FM IC (IC204). The IF signal is then mixed with the 2nd local oscillator frequency of 50.4MHz to generate the 2nd IF of 450kHz. The 450kHz signal is then passed through a ceramic ﬁ lter (CF201) and fed back into IC204 for additional ampliﬁ cation.

3-4. Wide/Narrow/P25 Switching Circuit

Wide, Narrow, and P25 settings can be made for each channel by switching the ceramic filters CF203 (Wide), CF204 (Narrow, P25), and there are controlled with the multiplexers (IC206, IC207).

When a W_/N Signal line is H, the 450kHz signal is passed through a ceramic ﬁ lter (CF203).

When a W_/N signal line is L, the 450kHz signal is passed through a ceramic ﬁ lter (CF204).

After that, the signal throughs ceramic ﬁ lter (CF250) and is fed into ASIC (IC10). And then, the signal is demodulated in ASIC, the AF signal is dealed with DSP (IC3).

The AF signal from ASIC (IC10) is ﬁ ltered for anti-aliasing and to eliminate unwanted spectrums to hear. Next, the AF signal goes through an electronic volume control (IC10) to be adjusted its level and a buffering AF ampliﬁ er IC506. Finally the AF signal into the audio power ampliﬁ er (IC11, 12).

4-1. Audio Band Circuit

The signal from the microphone passes through the mute switch (Q506) and AGC circuit (IC516, D511, D512, Q504, Q505), and goes to the summing ampliﬁ er (IC513), then is fed into ASIC (IC10) and converted from analogto digital. The digitalized signal undergoes AGC processing, pre-emphasizing, ﬁ ltering, vocording (in APCO mode), and returns to the ASIC (IC10). The signal is converted from digital to analog signal is ampliﬁ ed by ASIC (IC10). Then the signal adjusted to appropriate level passes through the buffer (IC512) and DAC (IC502), and goes to the VCO and VCXO in PLL section.

4-2. Base Band Circuit

The audio signal output from the base band circuit is con-

verted to digital data of a sampling frequency of 48kHz.

This digital data is sent to the DSP (IC3), and voice signals of 300Hz or lower and frequencies of 3kHz or higher are cut off and an audio range 300Hz to 3kHz is extracted. The audio signal is then pre-emphasized in FM mode and synthesized with the signals, such as QT and DQT, as required, and is then output from the ASIC (IC10). In Digital mode, the audio signal is converted to the C4FM base band signal and output from the IC10. The DTMF and MSK base band signals are also generated by the DSP and output by the IC10.

LPF (IC512) works as smoothing ﬁ lter. The DAC (IC502) assigns the base band signal to the VCO and VCXO (X301). At this time, the level output according to the transmit carrier is ﬁ ne-adjusted according to each modulation method.

4-3. Transmit Signal Ampliﬁ cation Circuit (From T/R switch to Final ampliﬁ er)

The transmit signal passing through the T/R switch (D101) is ampliﬁ ed to approx 100mW by the two transistor amplification circuits (Q101, Q102). The transmit signal output from Q102 passes through a 3dB attenuator to improve high-frequency signal matching is amplified by the drive amplifier (Q103) and applied to the final amplifier (Q105). The signal applied to the ﬁ nal ampliﬁ er is ampliﬁ ed by the ﬁ nal ampliﬁ er so that the antenna output is 5W (1W for Low Power).

4-4. High-Frequency Signal Switch Circuit (From Antenna switch to ANT output)

The transmit signal output from the ﬁ nal ampliﬁ er (Q105) passes through the antenna switch (D106, D107) and LPF, and goes into the SPDT switch (IC102, IC103) which changes the antenna connector (CN101) and the universal connector (CN102). The transmit signal passing through the output change switch passes through the surge protection HPF and spurious removing LPF and then goes to the antenna connector (CN101) or the universal connector (CN102), speciﬁ ed by the SPDT switch (IC102, IC103).

4-5. APC circuit

The APC circuit detects the current of the drive amplifier (Q103) and final amplifier (Q105) during transmission and controls the output power by controlling the current. It detects the current using R119 and R120 and applies a drop voltage between both resistors during transmission to APC IC (IC101). It controls the transmission current of the drive ampliﬁ er and ﬁ nal ampliﬁ er so that it is constant by comparing this current with the reference voltage output from pin 7 of IC104. The reference voltage input to pin 5 of IC104 is output from the DAC (IC502).

High/Low power output is set according to the DAC output voltage.

4-6. Temperature Protection Circuit

The temperature protection circuit reduces the APC voltage when the temperature of Q105 rises, to prevent thermal destruction of the ﬁ nal ampliﬁ er (Q105). The ASIC (IC10) detects the temperature with a thermistor (TH101) to control the reference voltage to the APC circuit.

5. PLL Frequency Synthesizer

5-1. VCXO (X301)

VCXO (X301) generates a reference frequency of

16.8MHz for the PLL frequency synthesizer. This reference frequency is applied to pin 8 of the PLL IC (IC303).

The VCXO oscillation frequency is ﬁ ne-adjusted by controlling the voltage applied to pin 1 of the VCXO with DAC (IC502). It is also controlled with pin 1 of the VCXO if the output from VCXO is modulated.

5-2. VCO

There is a RX VCO and a TX VCO.

The TX VCO (Q311) generates a transmit carrier and the RX VCO (Q310) generates a 1st local receive signal. For the VCO oscillation frequency, the transmit carrier is 272 to 348MHz and the 1st local receive signal is 371.9 to

IC101

R119

R120

APC

447.9MHz. The VCO oscillation frequency is determined by one sys-

tem of operation switching terminal “VCOSW1” and two systems of voltage control terminals “CV” and “ASSIST”. The operation switching terminal, “VCOSW1", is controlled by the ASIC (IC10). When the VCOSW1 logic is high, the RX VCO outputs the signal. And if the logic is low, TX VCO outputs the signal.

The voltage control terminals, “CV” and “ASSIST", are

controlled by the PLL IC (IC303) and rheostat (IC414) and the output frequency changes continuously according to the applied voltage. For the modulation input terminal, “VCO_ MOD”, the output frequency changes according to the applied voltage. This is used to modulate the VCO output. “VCO_MOD” works only when transmit is active (user pressed PTT).

APC SW

TK-5210(G

)

CIRCUIT DESCRIPTION

5-3. Rheostat (IC414)

The rheostat (IC414) is connected to the VCO voltage control terminal, “V-assist”, and quickly controls the VCO oscillation frequency. However, its accuracy is low and the VCO frequency cannot be matched accurately with the desired transmit carrier or the 1st local receive signal. The rheostat is controlled by the ASIC (IC10) through the 3-lines “PCS_pot”, “SDO0”, “SCK0” serial bus.

5-4. PLL IC (IC303)

PLL IC compares the differences in phases of the VCO oscillation frequency and the VCXO reference frequency, returns the difference to the VCO CV terminal and realizes the “Phase Locked Loop” for the return control. This allows the VCO oscillation frequency to accurately match (lock) the desired frequency.

When the frequency is controlled by the PLL, the frequency convergence time increases as the frequency difference increases when the set frequency is changed. To

supplement this, the ASIC (IC10) is used before control by the PLL IC to bring the VCO oscillation frequency close to the desired frequency. As a result, the VCO CV voltage does not change and is always stable at approx. 2.0V.

The desired frequency is set for the PLL IC by the ASIC through the 3-line “PCS_RF”, “SDO0”, “SCK0” serial bus. Whether the PLL IC is locked or not is monitored by the ASIC through the “PLD” signal line. If the VCO is not the desired frequency (unlock), the “PLD” logic is low.

5-5. Local Switch (D101, D210)

The connection destination of the signal output from the 1/2 driver (IC304) is changed with the diode switch (D101) that is controlled by the transmission power supply, 5T, and the diode switch (D210) that is controlled by the receive power supply, 5R.

If the 5T logic is high, it is connected to a send-side prepre-drive (Q101). If the 5T logic is low, it is connected to a receive-side mixer (IC202).

6. Control Circuit

The control circuit consists of the ASIC (IC10) and its pe-

ripheral circuits. IC10 mainly performs the following;

1) Switching between transmission and reception by PTT signal input.

2) Reading system, zone, frequency, and program data from the memory circuit.

3) Sending frequency program data to the PLL.

4) Controlling squelch on/off by the DC voltage from the squelch circuit.

5) Controlling the audio mute circuit by decode data input.

6-1. ASIC

The ASIC (IC10) is 32bit RISC processor, equipped with

peripheral function and ADC/DAC.

This CPU operates at 18.432MHz clock and 3.3V/1.5V DC. It controls the ﬂ ash memory, SRAM, DSP, the receive circuit, the transmitter circuit, the control circuit, and the display circuit and transfers data to or from an external device.

CIRCUIT DESCRIPTION

)

6-2. Memory Circuit

Memory circuit consists of the ASIC (IC10) and the SRAM (IC4), the ﬂ ash memory (IC1). The ﬂ ash memory has capacity of 32M-bit that contains the transceiver control program for the ASIC and stores the data. It also stores the data for transceiver channels and operating parameter that are written by the FPU. This program can be easily written from external devices. The SRAM has capacity of 1M-bit that contains work area and data area.

Flash memory

■

Note: The flash memory stores the data that is written by the FPU (KPG-95DG), tuning data (Deviation, Squelch, etc.), and ﬁ rmware program (User mode, Test mode, Tuning mode, etc.). This data must be rewritten when replacing the ﬂ ash memory.

SRAM (static memory)

■

Note: The SRAM has temporary data area and work area. When the power supply is off, it is backed up by an internal secondary lithium battery. Therefore, the save data does not break.

Real-time clock

■

The clock function is based on real-time clock IC (IC7). When the power supply is off, it is backed up by an internal secondary lithium battery

6-7. Battery Type Detection

The transceiver automatically detects the battery type, measuring the resistance between the S-terminal and GND terminal on the battery pack and changes the supplied voltage to the S-terminal as below. The ASIC (IC10) then detects the battery type.

6-8. VOX

The VOX function can be used only with an external microphone.

The VOX (Voice Operated Transmission) function detects voice input to the microphone and automatically switches between transmission and reception. However, if a scrambler board is installed (Extended Function Voice Scrambler is selected with FPU), VOX does not operate.

If the microphone input exceeds a certain level, transmission automatically begins. If the input falls below a certain level, the transceiver automatically returns to receive mode.

The transceiver realizes this function using DSP (IC8).

6-3. LCD

The LCD is controlled using the bus lines on the connector (CN1) of the control unit. The LCD contrast voltage is corrected using IC712.

6-4. Temperature Detection Circuit

The temperature detection circuit detects the temperature using a temperature IC (IC714) and corrects the thermal characteristic change of the squelch or LCD.

6-5. Key Detection Circuit

Keys are detected using Key scan circuit in IC10.

The /KEYI* signals that are normally pulled down go high when any key is pressed.

6-6. Low Battery Warning

The battery voltage is divided using R712 and R714 and is detected by the ASIC (IC10). When the battery voltage falls below the voltage set by the Low battery warning adjustment, the red LED blinks to notify the operator that it is time to replace the battery. If the battery voltage falls even more (approx. 5.8V), a beep sounds and transmission stops.

Low battery warning Battery condition

The red LED blinks during transmission.

The red LED blinks and the warning tone beeps while the PTT switch is pressed.

The battery voltage is low but the transceiver is still usable.

The battery voltage is low and the transceiver is not usable to make calls.

6-9. DSP

The DSP circuit consists of a DSP (IC3) and processes the base band signal. The DSP operates on an external clock of 18.432MHz (the same as the X2), the I/O section operates at 3.3V and the core section operates at 1.5V. The DSP carries out the following processes:

• C4FM

• Analog FM pre-emphasis/de-emphasis

• Vocoder processing between audio codec and modula-

tion/demodulation

• CAI processing, such as error correction encoding

• QT/DQT encoding/decoding

• DTMF encoding/decoding

• MSK encoding/decoding

• 2-tone encoding/encoding

• Compressor/expander processing

• Transmit/receive audio ﬁ ltering processing

• Microphone ampliﬁ er AGC processing

• Audio mute processing

• Modulation level processing

CIRCUIT DESCRIPTION

7. Power Supply Circuit

The power supply voltage (+B) is supplied from the bat-

tery terminal, and is then passed through the fuse (F700).

If +B voltage is detected above 5.6V by the voltage detection IC (IC16), IC17 CE pin (pin 6) becomes high and IC17 outputs 3.1V (pin 3). Additionally, when VOL SW is ON, the

3.6V and 15V DC/DC converter (IC707, IC708) CE pin (pin 4) becomes high and 3.6V power source turns ON.

The output from the 3.6V DC/DC converter (IC707) provides the power source for three regulators (IC705, IC706, IC710) and 1.5V DC/DC converter (IC709). After these parts became ON, Flash (IC1), DSP (IC3), SRAM (IC4), ASIC (IC10)

start to operate. After the ASIC starts up, it begins controlling three regulators (IC701, IC702, IC704) with the SBC and /SAVE signal. And after that, one regulator (IC700) is controlled by the 5M signal.

The output voltage from IC701 is switched by 5RC signal (which is turned on while receiving) or 5TC signal (which is turned on while transmitting). These signals are controlled by the ASIC (IC10).

The output voltage from IC700 is controlled by Q703 and Q704, and is used as a power source for 5MCS, for an optional accessory which is connected to the universal connector (CN505).

CIRCUIT DESCRIPTION

8. Signaling Circuit

8-1. Encode (QT/DQT/DTMF/2TONE /MSK)

Each signaling data signal of QT, DQT, DTMF, 2TONE and MSK is generated by the DSP circuit, superposed on a modulation signal and output from IC10. The modulation balance of the QT/DQT signal is adjusted by the D/A converter (IC502) and the resulting signal is routed to the modulation input of the VCO and VCXO (X301). The each deviation of the TX QT, DQT, DTMF, 2TONE and MSK tone is adjusted by changing the output level of the IC108 and the resulting signal is routed to VCO and VCXO. The RX DTMF tone is routed to the receive audio signal system, and is output from the speaker.

8-2. Decode (QT/DQT/DTMF/2TONE/MSK)

The audio signal is removed from the FM detection signal by ASIC (IC10), and resulting signal is decoded by DSP (IC3).

9. Compander Circuit

The term “compander” means compressor and expander. The compander reduces noise by utilizing a compressor and an expander. The transceiver contains a DSP (IC3) to perform this operation. The transceiver compander can be turned on or off using the FPU.
