CIRCUIT DESCRIPTION
1. A band receiver system
1-1. Receiver circuit
The A band can receive signals in two bands: VHF (220 MHz
band <K type only>) and UHF (K type: three bands). It uses
FM receive mode only, and uses double conversion with the
first IF of 59.85 MHz and the second IF of 450 kHz.
The first amplifier is divided into two bands: 137 MHz -
173.995 MHz (216 MHz - 260 MHz <K type only>) and 410 MHz
- 470 MHz. The incoming signal from the antenna passes
through a low-pass filter and a duplexer, and goes to an
independent amplifier (Q63, Q62) for each band.
1-1-1. VHF band frontend
The incoming signal from the antenna passes through a
VHF band low-pass filter and a duplexer, passes through a
band-pass filter where it is tuned with varicaps (D76, D77),
and goes to the first amplifier (Q63). Unwanted signal
components are eliminated by a two-pole band-pass filter
where it is tuned by varicaps (D72, D75, D81, D83), and the
signal goes to the common mixer (Q45) for the A band. (K
type only: For 200MHz band reception, D74 is turned off with
a control signal to improve band-pass filter coupling and
ensure pass bandwidth.)

1-1-3. Circuits following IF
The signal heterodowned to the first IF of 59.85 MHz by the
mixer (Q45) passes through a 15kHz MCF (XF2) and unwanted
signal components are eliminated. The resulting signal is
amplified by the IF amplifier (Q43) and goes to the FM IC (IC7).
The FM IC heterodowns it to the second IF of 450 kHz. Then,
the signal passes through a 15kHz external ceramic filter (CF4)
and goes to the FM IC again. The signal amplified by the IF
amplifier built into the IC is demodulated by the quadrature
FM demodulation circuit using a discriminator (CD1) and
converted into an audio signal and output.
The FM modulation signal output from the FM IC passes
through a low-pass filter consisting of a resistor and a capacitor
and is output to the control section. The demodulation signal
input to the control section goes to the electronic volume
(IC706, pin 13) to adjust the audio balance with the B band.
The output signal is amplified by the operational amplifier
(IC717), passes through an active filter consisting of Q719 and
Q717, and goes to the audio amplifier (IC707). The signal
amplified to a higher power by the audio amplifier becomes
the final output signal from the set and output through the
internal speaker or speaker output pin (J701).

The local oscillator signal for the first mixer is supplied from

The local oscillator signal for the second mixer is a 59.4
MHz signal that is produced by multiplying the 19.8MHz TCXO
(X1) oscillator output with a multiplier (Q44).
2. B band receiver system
2-1. Receiver circuit
The B band has a broadband receiver circuit configuration
and implements broadband reception of 100 kHz to 1.3 GHz.
FM/AM/SSB/CW reception is possible in the range 100 kHz to
29.7 MHz, and FM/wide FM/AM/SSB/CW reception is possible
in the range 29.7 MHz to 1.3 GHz. The FM/AM receiver circuit
uses double conversion with the first IF of 57.6 MHz and the
second IF of 450 kHz. The SSB/CW receiver circuit uses triple
conversion with the first IF of 57.6 MHz and the second IF of
450 kHz. The wide FM receiver circuit uses single conversion
with the IF of 10.8 MHz.
CIRCUIT DESCRIPTION
TH-F6A/F7E
The first amplifier is divided into four bands: 100 kHz - 50
MHz, 50MHz - 108MHz, 108 MHz - 265 MHz, 265 MHz - 600
MHz, and 600 MHz - 1.3 GHz. The incoming signal from the
antenna passes through a low-pass filter and a duplexer, and
goes to an independent amplifier for each band. Then, the
signal goes to the second common broadband amplifier (IC10)
and its output is fed to the mixer (Q28) and heterodowned to
the first IF.
2-1-1. FM/AM receiver circuit
The signal heterodowned to the first IF of 57.6MHz passes
through a 15kHz MCF (XF1), and unwanted signal components
are eliminated. The resulting signal is amplified by the IF
amplifier (Q26) and goes to the FM IC (IC5). The FM IC
heterodowns it to the second IF of 450 kHz. In FM mode, the
signal passes through a 12.0kHz external ceramic filter (CF3)
and goes to the FM IC. The signal amplified by the internal IF
amplifier is demodulated by the quadrature FM demodulation
circuit using a coil (L19) and converted into an audio signal
and output. In AM mode, the signal passes through a 4kHz
external ceramic filter CF1 and goes back to the FM IC. It is
amplified by the AM AGC amplifier built in the FM IC, an audio

This unit incorporates an AM bar antenna, and either the
bar antenna or the supplied antenna can be selected in the
520kHz-1.8MHz (SW) and 3.5MHz-10.1MHz (MW) bands (the
initial value: bar antenna). The bar antenna has two kinds of
tuners for SW and MW tuning, one of which is selected with a
switching FET (Q32, Q48, Q52). The antenna is tuned with a
varicap (D60) for AM tuning to select a desired signal. The
signal from the bar antenna is amplified by and its impedance
is converted by the buffer amplifier (Q59), and the resulting
signal goes to the common mixer (Q28) for the B band. The
signal is routed over the same path for AM demodulation as
for the supplied antenna after leaving the mixer.

2-2. Mixer local oscillator
2-2-1. First mixer
The local oscillator signal for the first mixer is supplied from
the VCO-PLL circuit. To offset according to modes, the PLL
switching frequency changes in FM/AM/CW, USB, LSB.

Table.1
2-2-2. Second mixer
The local oscillator signal of the second mixer uses
57.15MHz which is three times as high as the 19.05MHz crystal
oscillator (X3) output. This local oscillator signal is used to (i)
implement fine steps during fine tuning and (ii) offset during
SSB/CW reception.

* During fine tuning, it changes with 33.3 Hz step from PLL
Switching Frequency to the next Switching Frequency.
(i) Fine tuning function
When the fine tuning function is ON, the PLL comparison
frequency is 5 kHz (5kHz step). The "receive frequency of
10Hz steps as a set" is implemented by operating the local
oscillator signal of the second mixer in 33.3Hz steps in the
5kHz frequency range. The frequency is varied by 57.15
MHz +/- 2.5 kHz by changing the voltage applied to the
varicap (D29) installed in the local oscillator circuit.
(ii) Mode offset
The IF frequency is adjusted by 2 Hz in SSB mode so that
the demodulated signal passes through the center of the
4kHz ceramic filter (CF1). The frequency is adjusted by
varying the local oscillator frequency.

2-3. AGC circuit
The AGC is controlled by using the output from the RF AGC
built into the FM IC (IC5). The AGC is controlled by controlling
the bias current of the IF amplifier (Q26) and the forward
current of the pin diode (D32) for the attenuater. In non-FM
mode, the AM AGC circuit built-into the FM IC is also used.
3. Control
3-1. Reset and backup circuits
The CPU reset signal is generated with the CR time constant
by detecting a rising edge of the M4 line voltage with the
voltage detection IC (IC709). If the voltage supplied to the THF6/TH-F7 decreases and the M4 line voltage falls below the
detection voltage of the voltage detection IC (IC710), the CPU
(IC705) detects it through the interrupt pin, backs up data in
the EEPROM (IC704), and shuts the power off.
3-2. Voltage detection processing
The voltages are measured through the A/D port of the CPU
(IC705) for processing. The battery voltage is supplied through
a resistor, and a warning sound is produced when an abnormal
power supply voltage (17.5 to 22.0 V) is applied to the battery
meter during transmission. The squelch voltage is input from
the IF IC, and a change in the noise voltage is detected to
control squelch. The S meter voltage is input from the IF IC to
control the S meter display. Thermistor voltage (temperature)
detection, remote control microphone key operation, VOX
voltage monitoring, and TONE/DCS decoding are performed
through the A/D port.
3-3. VOX
The signal output from the microphone amplifier (IC702) is
amplified by Q701, rectified/integrated by D709 to convert to
DC voltage, and monitored through the A/D port of the CPU
(IC705) to perform VOX processing.
3-4. Battery save
The CPU (IC705) controls Q728 through the SAVE port to
save battery power.
3-5. LED drive circuit
The CPU (IC705) controls Q709 to turn LEDs on to illuminate
the LCD and keys. The ON AIR/BUSY LED is directly controlled
through the open drain port of the CPU (IC705).
CIRCUIT DESCRIPTION
TH-F6A/F7E
3-6. Key/encoder input circuit
The PWR key is assigned to an interrupt port. The PTT key
is assigned to another interrupt port. The other keys and
destination diodes form a 5x6 matrix and pressing a key is
detected by scanning the matrix by software. The encoder
reads data through the interrupt port.
3-7. CTCSS/DCS
The encode signal is output from the D/A port of the CPU
(IC705) by software. The signal level is adjusted with an
electronic VR (IC706) and the signal is divided into VCO and
TCXO and modulated like a 9600bps packet signal.
The audio signal from the IF IC passes through the IC712/
IC711 waveform rectification circuit and enters the A/D port
of the CPU (IC705). The CPU detects that the specified CTCSS
tone frequency and DCS code are detected and controls
muting.
4. PLL • VCO
The TH-F6/TH-F7 has two PLL loops and a total of four VCOs,
two for each PLL loop. The PLL is divided for A band reception,
B band reception and transmission. Each VCO has oscillator
frequency shift control. For relationships between VCO
oscillator frequencies and shifts, see Table 4-11.
3-8. DTMF
The DTMF signal is output from the D/A port of the CPU
(IC705) by software means. The signal is mixed with a signal
at the input side of the audio amplifier (IC707) and output as a
monitor tone. It is mixed with a modulation signal at the input
side of the preemphasis (IC701) and used to as a transmit
signal.
3-9. Serial control
The REM/PTT terminal of the speaker mic jack (J701) is
switched by the CPU (IC705) and functions as TXT/RXD to
communicate with a personal computer.
TH-F6A Frequency Construction
A band RX Double Super Heterodyne
IC6 functions as A band reception PLL. This PLL IC controls
the VCO produced by Q34. VCOs are changed over by
switching the power provided to each VCO by Q35 through
control line "DAVCOS" from the CPU. VCO power passes
through a ripple filter consisting of Q31 and C235.

IC2 functions as B band reception PLL. This PLL IC controls
the VCO produced by Q9. VCOs are changed over by switching
the power supplied to each VCO by Q10 through control line
"DBSS" from the CPU. VCO power passes through a ripple
filter consisting of Q7 and C52. Each VCO output is amplified
by a common amplifier (Q13).
4-2-1. 0.1MHz-267MHz reception, VHF (220MHz <K type
only>) band transmission
The VCO oscillator frequency is UHF. The signal output
from Q13 goes to the prescaler IC (IC3) and is divided into 1/8
(0.1MHz-23MHz), 1/4 (23MHz-104MHz), and 1/2 (104MHz267MHz). Division is controlled by using control signals "SW1
(Q15)" and "SW2 (Q15)" from the CPU. The division output is
amplified by an amplifier (Q19), and the signal goes to the
mixer (Q28) during reception and to the drive during
transmission. The PLL IC FIN input is generated by extracting
the output from Q13 and amplifying it with an amplifier (Q11).

CIRCUIT DESCRIPTION
5. Lithium ion battery charging control
If a lithium ion battery is installed, it is charged when power
is supplied to the DCIN JACK from outside. The mechanism
of charging control is described below.
When power is provided to the DCIN JACK, Q65 turns ON
and the control port is made LOW to notify the CPU of
connection of an external power source. The CPU grounds
the Q2 collector according to this information. As a result, Q5
turns OFF and Q1 turns ON. If the remaining battery level is
low, the Q1 collector current increases, so the emitter voltage
is reduced by R2 and Q2 turns ON to charge the battery
(charging). The CPU pulls up the Q2 collector voltage, uses
this port as input, and monitors it. If the battery voltage level
increases, the Q1 collector current decreases, the emitter
voltage drops and Q2 turns OFF at a certain voltage. The CPU
recognizes that charging is approaching its end by this change,
and enters an additional charging state. In the additional
charging state, the CPU grounds the Q2 collector and
continues charging slowly in about an hour. When it ends,
the battery charging is complete.
IC1 is a lithium ion battery charge control IC. When the
battery voltage exceeds 8.4 V, the output port is made HIGH
and Q3 is turned OFF to stop charging. If it is 8.4 V or lower,
"LOW" is output and Q3 is turned ON to bias Q1.

6. Receive audio circuit
The receive signal demodulated by the FM IC on each of
the A and B bands passes through an electronic volume (IC706)
and is amplified by IC717. The signal is deemphasized by
Q719, passes through a variable RESISTOR (AFVR), is
amplified by the audio amplifier (IC707), and output to the
speaker (SP1) or external speaker jack (J701).
CTCSS or DCS is a 2-channel multiplexer from FM IC output,
and A or B band is selected, the signal passes through an
amplifier filter (IC711), and goes to the CPU where it is
decoded.

7. Transmission signal system
7-1. Modulation circuit
The audio modulation input is switched between external
input and internal microphone using an external microphone
terminal, and its base band is processed by microphone
amplifier IC 702 and preemphasis/limiter IC 701. The signal is
mixed with a DTMF subtone before the preemphasis circuit,
the level is adjusted by electronic VR IC706, and the signal is
input to the VCO as a modulation signal. The excessive input
of the 9600bps packet signal and the high-speed FM mode
12
The 9600bps packet signal is produced by converting the
impedance of the output signal from the FM IC by Q720 and
Q721, passing it through the Q722 switch, and outputting it to
the speaker (SP1) or external speaker jack (J701).

SSTV transmit signal input through the external microphone
input terminal is suppressed by D710 and D711, switched by
IC703, and input to electronic VR IC706. The level-adjusted
signal is amplified by Q719, passes through electronic VR
IC706, and is divided into two paths: one for modulating the
VCO through electronic VR IC706 the other for modulating
TCXO X1 through amplifier IC702 to perform broadband
transmission modulation.

7-2. Transmission circuit
For the VHF VCO output, the 500MHz output passes through
the RF amplifier (Q13), is divided into 1/4 and amplified by
Q19. The signal passes through switch D101/D102, is amplified
by four amplifiers Q71, Q72, Q54, and Q56, and amplified to
the final output by power amplifier Q55. The signal passes
through a low-pass filter, an antenna switch, and another lowpass filter, and is sent to the antenna.
[(K only) The 220MHz VCO output is produced by passing
the 400MHz output through the RF amplifier (Q13), dividing it
into 1/2 by IC3, and amplifying it by Q19. The signal passes
through a switch (D101/D102), is amplified by four amplifiers
Q71/Q72/Q54/Q56, and amplified to the final output by power
amplifier Q57. The signal passes through a low-pass filter, an
antenna switch, and another low-pass filter, and is supplied
to the antenna.]

7-3. APC circuit
The APC circuit is used to provide stable transmission
output, detects drain current of the power module and controls
transmission output. The voltage produced at R204, and R206
is amplified by IC8 and Q50, and the difference between the
voltage and the reference voltage of each band/power output
from the CPU (IC705) is detected by IC9 to produce APC
voltage. This voltage controls the gain of Q54, Q56, Q55, and
Q57.
Fig.20
7-4. Temperature protection circuit
To prevent thermal destruction of the final power amplifier,
the voltage of the thermistor TH1 installed near the power
module is monitored by the CPU IC705. If the prescribed
temperature is exceeded, the APC voltage is decreased to
reduce heat generation.
