4. Description of Frequency Determining and Stabilizing Circuit
4-1. Introduction
The Frequencies for transmitter and receiver first local frequencies are all derived from a signal
4.5MHz crystal by means of a phase locked loop(PLL).
The first local oscillator frequencies are 37.660MHz(CH1) to 38.10MHz(CH40). The second local
frequency is fixed at 10.240MHz to generate second IF 455KHz.
Transmit, the VCO of the PLL operates 26.965MHz(CH1) to 27.405MHz(40CH). The VCO frequency
goes to the Buffer Amp circuit Q134, L701.
Q128
VCO
26.965MHz(CH1)
~
27.405MHz(CH40)
The VCO operating frequency for the receiver is 37.66MHz(CH1) to 38.10MHz(CH40) as the
first local oscillator, injected through the buffer amplifier Q129 into the first FET balanced mixer Q102,
Q103.
4-2. Basic Synthesis Scheme
The crystal frequency(4.5MHz) is divided by 1800 times to make 2.5KHz which is fed to one
side of the phase detector. The VCO output is divided by a programmable divider, and fed to other side of
the phase detector Pin 9, 10 of IC4. Passing the phase detector output closes the feedback loop through
an active low pass filter and using the output to control the VCO frequency through varicap diode D112.
Under locked conditions, both of phase detector input signal must be identical at 2.5KHz.
The VCO frequency is then given by ;
Receiver : Fvco / N = 0.005 [MHz] OR Fvco = 0.005 X N [MHz]
Transmitter : Fvco / N = 0.005 [MHz] OR Fvco = 0.005 X N [MHz]
Since “N” is an integer, the VCO frequency can be stepped up with in receiver mode 5KHz and
transmitter mode 5KHz increments.
By suitable choice of “N” the desired output frequency can be obtained.

4-3. Descriptions of Each Block
4-3-1. Introduction
The synthesizer is implemented with the following components;
PLL IC (IC4)
X-TAL (X102)
VCO, VARICAP DIODE (D112)
IC4 is CMOS LSI that includes most of PLL block.
The Q128, L301, C232, C242, C243, C244, varicap diode D112 are clap oscillator circuit to
operate as a VCO of the IC4. Q127 is a switching transistor to connect or disconnect the tuning
capacitor in the VCO oscillator tank circuit for transmitter or receiver.
Q129 works as a buffer amplifier for RX local frequencies (≒37MHz) and TX carrier
generating frequencies(≒26MHz)
4-3-2. Reference Frequency
The crystal X102(4.5MHz) and other components at Pin 1 and 24 of IC4 can make a reference
frequency oscillator with internal amplifier.
4-3-3. VCO
Q128 and surrounding parts are consisting a clap oscillator works as a VCO of IC4. With
appropriate control voltage on D112 the VCO can be oscillate over the required range of 26.965MHz to
38.10MHz.
4-3-4. Programmable Divider and Its Control
The programmable input for each channel are stetted by the PLL Clock(Pin 56), PLL Data(Pin
55), PLL Enable(Pin 58) of IC12. Each input signal to control the PLL ic is done with provide key input
Pin 73, 74, 75. For each key input, an internal code converts EEPROM
appropriate control to the programmable divider for that channel.
Since the change transmit and receive, and additional bit is required at Pin 66 of IC12 to allow
the ROM to recognize the status TX or RX.
During transmit the push to talk switch makes Pin 66 ground, PLL IC works
under transmit status.
The programmable divider output fed to the phase detector for compare with the 5KHz
reference frequency IC4. See table 1 for actual input and divide ratio on all channels.
4-3-5. Phase Detector and VCO Control
The phase detector is a digital phase comparator witch compares the phase of the reference
signal with programmable divider output square waves and develops a series of pulses whose dc level
depends on the phase error of each signal.
The phase detector pulse output is fed to an active low pass filter and RC low pass filter output
signal of IC4 is filtered and fed to varicap D112 control the VCO frequency.
4-3-6. Transmitter / Receiver Buffer AMP
Output signal of Q128 is fed into the buffer amplifier Q129, L3 to generate TX carrier
frequency and 1’st local frequencies.
TTI 2009-02-20
Page 13
TCB-1100 Circuit Description Page 10
4-3-7. Transmitter Buffer
The output signal of Q129, L3 goes to an amplifier with tuning circuit Q134, L701,
which buffer incoming 26MHz signals.
4-3-8. Switching of Turning Capacitor in VCO
The VCO circuit must tune with a wide range of frequencies 26.965MHz ~ 27.405MHz for
transmitter and 37.66MHz ~38.10MHz for receiver.
To comply above range of VCO, the tuning capacitance should switch for transmission. The
tuning circuit consists with L301, C232, C242, C243, and C244. When the VCO is working as a receiver
Q127 becomes turn OFF. So, L301 and C232, D112 makes turning function.
When transmitting, Q127 becomes ON. S the o, L301 an parallel capacitance of C232 and C241
make turning function.
4-3-9. Receiver Local Oscillator Outputs
z FIRST MIXER :
The secondary output signal of L107 is injected to the sources of 1’st mixer Q102, Q103 in the
1’st IF mixer section.
z SECOND MIXER :
The output of 10.24MHz oscillator circuit with X101 is injected into the IF IC(IC1) internally.
Incoming IF signal and 10.24MHz signal are mixed inside the IF IC to extract 2’nd IF signal 455KHz.
FM audio Signals are recovered with the way of quadrature detector.
AM signals are recovered with envelope detector.
4-4. Frequency Stability
Let : Fo = Crystal oscillator frequency
Fr = Phase detector reference frequency
Fvco = VCO frequency
Ft = Transmit frequency
Then : Receiver : Fr = Fo/900
Transmitter : Fr = Fo/900
And under locked conditions : Fr = Fvco / N
Where, “N” is the programmable divider divide ratio.
Then : Fvco = N X Fr)
From which it can be seen, the percentage error in Ft is the same as the percentage error in Fo.
The stability of the crystal oscillator is determined primarily by the crystal itself and having lesser
deviation by the active and passive components of the oscillator. The choice of crystal and components is
such that the required frequency stability is maintained over the required voltage and temperature range.

4-5. Description of other Circuits
4-5-1. Transmitter
A. RF Amplification
RF carrier frequencies are obtained at the output of buffer amplifier Q134 and turning IFT coil
L701, The input of VCO frequencies 26MHz is selected at the buffer output,
The output of buffer amplifier Q134 is fed through turning IFT coil L701, L703 to the base of pre driver
amplifier Q135. It’s output; 27MHz is coupled to RF driver amplifier Q136, a low-level class C power
amplifier. Driver Q136 supplies the necessary power gain to operate RF final Q138 at
the maximum efficient. The output of Q138 is supplied to the antenna through L-C turning circuit.
B. Circuit for Suppression of Spurious Radiation
The turning circuit between the output of final amplifier Q138 and antenna, 4-stage “π”
network C322, C323, C324, L711, C325, C326, L712, C328, C329, L713, C331, C332, C333, L714,
C334 serves as a spurious radiation suppressor. This network also servers to match the impedance
between TX power amplifier Q138 and the antenna.
C. Circuits for Limiting Power
After finished all alignment, the constant voltage supply circuit limits the available power 4W or
slightly less. RV106 and corresponding three-transistor control supply voltage of RF power amplifier.
When power low switch function Q145 changed the supply voltage. Tune all the trimming parts for
maximum indication of RF power meter and adjust RV104 to make 4W indication of RF power meter.
After finishing the above adjustments check the RF power meter reading is changed 1W under “LOW”
state.
The turning is adjustment so that the actual power is from 3.8W to 4.0W. There are no other
additional controls for adjusting the TX output power.
D. Modulation Control
Modulation of the RF is a process that begins with the audio picked up by the microphone.
<FM>
The microphone input is fed to mic audio amplifier IC5 that drives modulation vricap diode
D113 in the VCO circuit RV107 limits the incoming modulation audio levels to inhibit over modulation.
While reading the modulation factor on the modulation analyzing equipment, adjustment RV107 shall not
exceed 2.0KHz deviation.
<AM>
Modulation signals are filtered with RC network and goes to the audio power amplifier IC3 in
to make normal signal level to achieve wanted modulation. IC3 drives T101, which is a combination
AF output/modulation transformer. During transmit, one of the secondary windings of T101 is tied
between the 13.2V DC supply and the collectors of RF driver Q136 and RF power amplifier Q138. As the
audio passes through T101 it causes the collector supplies of Q136 and Q138 to vary with audio,
producing an AM signal at carrier frequency.
To avoid over modulation of the carrier, a protection of the modulating signal is fed back from
the T101 through the AMC circuit, Q119 and Q120, to control the gain of IC3 and sets the maximum
level of modulation. Form the center tab of RV102 and Q120 the feedback signal is rectified by diode
D109, filtered by C202, and supplied the Q119. The collector of Q119 is tied directly TX audio input to
control gain. That is, when the audio output is higher that the preset level of RV102, the information is
reflected through Q119 and Q120, reducing the gain of IC3

TCB-1100 Circuit Description Page 12
4-5-2. Receiver
Overload protection is provided to receiver’s semiconductors by diode D101. These diodes have
a little effect on the incoming signal from another CB station; they protect the receiver from stray
transmitter energy.
In the receiver mode of operation, Q142 transistor is turned on. Also bias voltage is applied to
Q101, Q102, Q103, IC1.
Q101 is a 27MHz RF input amplifier, and any excessive input signal is limited by diode D101.
CB receiver is dual conversion super-heterodyne type with the first IF 10.695MHz and the
second IF 455KHz.
Receiver is separated to blocks, 1’st IF section and 2’nd IF section. The PLL synthesizer
supplies 1’st local frequency 37.660MHz ~ 38.10MHz. The amplified 27MHz is mixed. With the
provide 1’st local frequencies Q102, Q103 mixes the incoming RF signal to generate 1’st IF signal. The
resulting first IF is 10.695MHz. Q102 and Q103 is the first converter, and 10.695MHz is sharply filtered
by L108 and crystal filter XF101. The first IF is again mixed with a second local oscillator of 10.24MHz.
With the 10.240MHz signal, IC1 FM IF IC converts the incoming signals to generate 2’nd IF
signal and recovered audio signals. 2’nd IF is filtered by a razor sharp ceramic filter CF101 coupled. The
455KHz signal from the 2’nd IF filter was amplified and limits internally. After amplification the signals
fed to the quardrature detector loop L109. Then could see the recovered signals Pin 8 of IC1.
With the amplitude of recovered signals, Q111 serves as an amplifier.
AM signals from the Pin 5 of IC1 were tapped with C135 and amplified two-stage amplifier
Q114, Q115. Q114 is a first 455KHz amplifier, and the Q114 being the last amplifier. D107 is a detector
diode witch produce audio signal as well as negative DC voltage for AGC action. The negative voltage
also provides forward biasing to the emitter of ANL clipping transistor Q116. The biasing voltage has a
time constant determined R162 and C168. Therefore any sharp negative going pulse from D107 will back
bias Q116 and clipped. The way to recover the AM information audio is envelope detector.
