TK-5400
CIRCUIT DESCRIPTION
1. Overview
The KENWOOD model TK-5400 is an 800MHz/FM/APCO
hand-held transceiver designed to operate in the frequency
range of 806 to 825MHz (TX)., 851 to 870MHz (TX/RX), the
unit consists of a receiver, a transmitter, a phase-locked
loop (PLL) frequency synthesizer, base band parts, power
supply circuits, a control unit.
2. Circuit Configuration by Frequency
The receiver is a double-conversion superheterodyne using first intermediate frequency (IF) of 44.85MHz and second IF of 455kHz. Incoming signals from the antenna are
mixed with the local signal from the PLL circuit to produce
the first IF of 44.85MHz.
This is then mixed with the 44.395MHz second local oscillator output to produce the 455kHz 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
amplified and fed to the antenna.

The VCO oscillation frequencies are 403 to 412.5MHz
and 425.5 to 435MHz, and locking occurs at both ranges of
doubled frequencies of 806 to 825MHz and 851 to 870MHz.
The VCO output components, other than the doubled frequencies, are eliminated by a band-pass filter, and the resulting signal is amplified by a buffer amplifier (Q201) and
routed to pin 5 of the PLL IC. The VCO output is amplified
by two buffer amplifiers (Q205, Q206) and routed to the
transmit drive stage and receiver mixer through the TX/RX
switch (D101, D102).
The PLL IC consists of a prescaler, a fractional divider, a
reference divider, phase a comparator and a charge pump.
The PLL IC is a fractional N type synthesizer and operates at
100kHz, which is 8 times the 12.5kHz channel step. The
input signal from pins 5 and 16 of the PLL IC are divided to
100kHz in the PLL IC and compared with a phase comparator. The pulse output signal of the phase comparator is applied to the charge pump and converted to a DC signal with
a loop filter (LPF). The DC signal is applied to pin 4 of the
VCO and locked to keep the VCO at a fixed frequency.
The PLL division data is output from DPM (pin 29), CPM
(pin 30) and EPM (pin 31) of the microprocessor (IC507),
converted by level converters (IC201, IC203, IC202) and input to the PLL IC. This division data is fed to the PLL IC
when the channel is changed or when transmission is
switched to reception. The PLL frequency lock state is always monitored with pin 78 (UL) of the microprocessor.
When the PLL is unlocked, the UL goes Low.
When the TK-5400 is operated for Talk Around, the transmit frequency is 851 to 870MHz, so pin 5 (TA) of the VCO is
made Low during transmission and the VCO oscillation frequency band is switched. The control signal that is sent to
pin 5 of the VCO is output from the shift register IC (IC701)
controlled by the microprocessor, and a High signal is output
except for Talk Around transmission.
Fig. 1 Frequency configuration
3.PLL Frequency Synthesizer
The PLL frequency synthesizer of the TK-5400 transceiver consists of a VCXO (X201), a VCO (L702), a PLL IC
(IC204) and a buffer amplifier (Q201).
The PLL reference oscillator VCXO produces 16.8MHz
and its frequency stability is 1.5 ppm or less (Temperature
range –30 to +60°C). VCXO frequency tuning and modula-
tion are performed by applying voltage to pin 1 of the VCXO.
The VCXO oscillation output is applied to pin 16 of the PLL
IC.

CIRCUIT DESCRIPTION
TK-5400
4. Power Supply Circuit
The battery power (+B) is supplied from the battery terminal to the TX-RX unit through a 3A fuse. The power (SB)
that passes through the power supply are routed to three
AVR ICs (IC702, IC704, IC705), the DC/DC converter IC
(C402) and the power transistor switch (Q5,Q6 : Control
unit) for the audio amplifier IC. It is then reduced to 3.8V by
the DC/DC converter IC and the signal goes to the three
AVR ICs (IC403, IC404, IC405).
5C is common 5V. Unless SAVE is set to OFF, 5V is always output. 5R is 5V for the receive circuitry and 5V is
supplied to the RF receive circuit during reception. 5T and
5TB are 5V for the transmit circuitry and 5V is supplied to the
RF transmit circuit during transmission. 5M supplies 5V to
the shared circuits. 33D mainly provides 3.3V to the microprocessor (IC507), DSP (IC611) I/O section and memory IC
(IC508). 25D supplies 2.5V to the DSP core. 33A mainly
supplies 3.3V to the A/D converter IC (IC609) for reception
and the codec IC (IC608). 33AR provides 3.3V to the 2nd IF
amplifier (IC302) for reception.
The power (Vp) switched from the SB by Q5 and Q6 (control unit) supplies approx. 7V to the audio amplifier IC (IC1).
The transmit power amplifier power supply (Vd) provides
approx. 7.2V from +B through the 3A fuse and current detection resistor.
5. Receiver System
5-1. Front-end RF Amplifier
The signal are passed through an antenna matching coil,
where the high-frequency components are amplified by a
dual gate FET (Q302). The signals are then fed through the
band-pass filter (L302, L307) to reject unwanted signal components, and is fed to the 1st mixer.
5-2. First Mixer
The 1st mixer uses the IC (IC301). The 1st mixer mixes
the signal with the signal 1st local oscillator frequency from
the VCO, and converts it to the 1st IF (44.85MHz).
The signal then passes through monolithic crystal filter
(XF301) to remove unnecessary nearby frequency components. The signal from the MCF is used as the 1st IF signal.

CIRCUIT DESCRIPTION
5-3. IF Amplifier
The 1st IF signal is amplified (Q304) and fed into IC303 in
the MIX, IF AMP IC. The IF signal is then mixed with the
2nd local oscillator frequency of 44.395MHz to generate the
2nd IF of 455kHz. The 455kHz signal is then passed through
a ceramic filter (CF301) and fed back into IC303 for additional amplification. Again the 455kHz signal is then passed
through a ceramic filter (CF302).
5-4. Digital Signal Processor (DSP) Demodulation
Processing
The 455kHz signal that passes through the ceramic filter
is amplified to the appropriate value by the 2nd IF amplifier
and fed to ADC (pin 6 of IC609). The base band signal A/Dconverted at the ADC is processed by the DSP (IC611).
The DSP performs FM demodulation for FM signals and
C4FM demodulation for C4FM signals. Then, the base band
signal is D/A-converted and an AF signal is output from
CODEC (pin 15 of IC608).
The D/A-converted noise component enters the SW (pin
5 of IC706) through CODEC (pin 16 of IC608) and is output
as a squelch noise signal.

5-6. Audio Amplifier Circuit
• TX-RX unit
The converted D/A signal from IC608 is amplified by AF
amplifier IC606 (2/2). The signal then goes through an electronic volume control (IC605), an AF amplifier IC607 (2/2),
and an AF switch (Q8 is on and Q7 is on/off the control unit),
and is routed to audio power amplifier (IC1 of the control
unit), where the signal is amplified and output to the internal
speaker.
• Control unit
The audio mute signal (AMP SW) from the microprocessor becomes Low in the standby mode and Q5 and Q6 in
the power supply circuit for IC1 are turned off. When the
audio outputs, AMP SW becomes High to turn Q5 and Q6
on, and the DC is supplied to power terminal VP of IC1.
Speaker switching is performed by the IC701 (TX-RX unit)
using INT AFC or EXT AFC. First, the logic level at the
speakers switching terminal (SSW) on the universal connector is fed to the microprocessor (IC507 TX-RX unit). The microprocessor then outputs data to IC701 based on this input.
When there is no SP-MIC installed, this logic level becomes high. When the INT AFC is high, the EXT AFC goes
low, so the AF signal is only fed to the amplifier for the internal speaker (INT SP) of IC1.
However, when a SP-MIC has been connected, this logic
level becomes low, so the INT AFC goes low and the EXT
AFC goes high. In this case, the AF signal is fed only to
amplifier for the external speaker (EXT SP) of IC1.
5-5. Squelch Circuit
The output from the SW (IC706 pin 6), goes through a
low-pass filter (IC601 2/2). The noise component from
IC601 (2/2) is amplified by Q602 and rectified by D602 to
produce a DC voltage corresponding to the noise level. The
DC voltage is fed to the CPU (IC507 pin 88).

CIRCUIT DESCRIPTION

6. Transmitter System
6-1. Microphone Amplifier
The signal from the noise canceller amplifier (control unit
IC3) passes through the MIC changeover circuit (Q711), the
mute switch (Q713) and the AGC circuit, and goes to the
microphone amplifier IC (IC602).
When an accessory speaker microphone (SP-MIC) is not
installed, the microphone switching terminal (MSW/CTS)
goes high and the microphone changeover switch (Q711)
turns on. When the SP-MIC is installed, the MSW/CTS is
connected to GND in the SP-MIC, Q711 turns off, the internal microphone is muted and only the external microphone
input is supplied to the microphone amplifier of the TX-RX
unit.
The AGC circuit consists of IC602 (1/2), D600, D601,
Q600 and Q601. The AGC is operated by using the current
obtained by detecting positive or negative polarity of the audio signal amplified by IC602 (1/2) and controlling the positive (+) and negative (–) level of the amplifier.
The transmit audio signal output from IC602 (2/2) is input
to pin 3 (AINL) of the codec IC (IC608) and converted from
analog to digital. The digitalized transmit audio signal undergoes AGC processing, pre-emphasizing, filtering, vocoding
(in APCO mode), and returns to the codec IC (IC608). The
signal is converted from digital to analog and an analog signal (C4FM base band signal in APCO mode) is output from
pin 16 (AOUTR).
The audio signal that is DSP-processed by the codec IC
(IC608) and DSP (IC611) passes through the analog switch
(IC706) and amplifier (IC606, IC604) and goes to the D/A
converter (IC605). The audio signal whose maximum deviation is adjusted by the D/A converter passes through the AF
switch (Q202 is off in TX mode) and goes to VCO modulation input. The audio signal whose modulation balance is
adjusted by the D/A converter passes through a buffer amplifier (IC607) and goes to VCXO modulation input.

6-2. Noise Cancelling Microphone Circuit
The two signals from INT MIC (Main & Sub) are fed to the
positive (+) input (Sub) and to the negative (–) input (Main) of
the IC3. If the same signals is fed to both Main and Sub, the
Main signal is terminated at the output of IC3 (pin7). In another words, noise from nearby sources not directly connected to the transceiver enters the Main and Sub input at
the same signals and is therefore canceled out.
When a signal is only fed to the Main and there is no
signal at the Sub, IC3 (pin 7) outputs the Main signal as it is.
In other words, only the voice audio of the operator to the
Main MIC is input to the Main so that “N/C” switch is set to
“L”, transistor Q14 is turned off and the Sub microphone
also is turned off and the operation is same as above.
6-3. Drive and Final Amplifier
The signal from the T/R switch (D101 is active) is amplified by the pre-drive (Q101) and drive amplifier (Q103) to
50mW. The drive amplifier output is amplified by the RF
power amplifier (Q1, Q2, Q3) to 3W (1W when the power is
low).
The RF power amplifier has two-stage MOS FET transistor. The output of the RF power amplifier is then passed
through the Transmit-Receive (TX-RX) antenna switching
(D103 is active) and low-pass filter (LPF) and applied to the
antenna terminal.
6-4. APC Circuit
The APC circuit always monitors the current flow through
the RF power amplifier (Q1, Q2 or Q3) and maintains a constant current. The voltage drop at R101, R102 and R103 is
caused by the current flow through the RF power amplifier
and this voltage is applied to the differential amplifier (IC101
1/2).
IC101 (2/2) compares the output voltage of IC101 (1/2)
with the reference voltage from IC605. The output of IC101
(2/2) controls the voltages the VGG of the RF power amplifier to make the both voltages to same voltage.
The power high/low switching is carried out by changing
the reference voltage. The Q102, Q104 and Q105 are
turned on in transmit and the APC circuit is active.

CIRCUIT DESCRIPTION
7. Control Circuit
The control unit has microprocessor IC507, flash
memory IC508, and its peripheral circuits. It controls the TXRX unit and transfers data to and from the control unit. The
CPU (IC507) mainly performs the following:
1) Switch between transmission and reception with the PTT
signal input.
2) Read a channel, frequency, and program data from the
memory circuit.
3) Send a frequency program data to the PLL.
4) Control the audio mute circuit by decode data input.
5) Send serial data to output expander (IC701, IC703) to
control various function in the unit.
7-1. CPU
The CPU (IC507) is a 16bit single-chip microprocessor,
equipped with a 64k ROM and 10k RAM. This CPU operates at 12.288MHz clock and 3.3V DC. Controls the flash
memory IC, the DSP, the receive circuit, the transmitter circuit, the control circuit, and the display circuit and transfers
data to or from an external device.
7-2. Memory Circuit
IC508 is a flash memory with 8M bits capacity that stores
the transceiver control program for the CPU and the data
such as transceiver channels and operating parameters.
This program can be easily written from an external devices. The data, such as DTMF memories and operating
parameters, are stored into the EEPROM (IC505).
7-4. D/A Converter
IC605 is used as a conventional semi-fixed-resister con-
verter. It controls the followings:
1) Transmission power
2) Modulation level
3) Audio power
4) Frequency
7-5. Key Input
Kl1 or Kl2 becomes HIGH when a key is pressed (or En-
able signal on the optional circuit).
When Kl1 or Kl2 becomes HIGH, Kl0 also becomes HIGH
to trigger the interrupt to IC507 in order to start the key
scan.
When the key scan starts, the output terminals (Q1~Q5)
become LOW. Only the key sensing circuit remains HIGH.
When a key is pressed, the signal routed through Kl1 or Kl2
to the microprocessor. Then, the microprocessor determines which key is pressed using this signals.

CIRCUIT DESCRIPTION / SEMICONDUCTOR DATA
7-7. DSP
The DSP circuit consists of a DSP (IC611), a codec
(IC608), and an A/D converter (IC609) and processes the
base band signal. The DSP (IC611) operates on an external
clock of 12.288MHz (the same as the CPU), the I/O section
operates at 3.3V and the core section operates at 2.5V. The
DSP carries out the following processes:
• C4FM modulation and demodulation
• Analog FM modulation and demodulation
• Vocoder (IMBE) processing between audio codec and
modulation/demodulation
• CAI processing, such as error correction encoding
• QT/DQT encoding/decoding
• DTMF encoding
• Compressor/expander processing
• Transmit/receive audio filtering processing
• VOX processing
• Microphone amplifier AGC processing
• Beep tone generation, audio mute processing
• Modulation level processing
8. Signaling Circuit
8-1. Encode (QT/DQT/DTMF)
Each signaling data signal of QT, DQT and DTMF is generated by the DSP circuit, superposed on a modulation signal and output from pin 16 of the codec IC (IC608).
The modulation balance of the QT/DQT signal is adjusted
by the D/A converter (IC605) and the resulting signal is
routed to the modulation input of the VCO (L702) and VCXO
(X201).
The DTMF deviation of the TX DTMF tone is adjusted by
the D/A converter (IC605) and the resulting signal is routed
to VCO and VCXO. The RX DTMF tone is output from pin 15
of the codec IC, passes through the receive audio signal system, and is output from the speaker.
8-2. Decode (QT/DQT)
The audio signal is removed from the FM detection signal
sent to the DSP circuit and the resulting signal is decoded.
9. Compander Circuit
The term “compander” means compressor and expander. The compander reduces noise by utilizing a compressor and an expander.
The TK-5400 contains DSP IC (IC611) to perform this operation. The TK-5400 compander can be turned on or off
using the FPU.
