SECTION 3 CIRCUIT DESCRIPTION
GENERAL INFORMATION
The TX-446 has four printed circuitboards. (Main PCB, SW PCB and two BATT PCB in battery pack.)
Circuitry is described in the following order: Microprocessor/Control Section, VCO/Synthesizer Section,
Transmitter Section, Receiver Section and Battery Section. Refer to the Block Diagram and the Schematics.
3-1 MICROPROCESSOR / CONTROL SECTION
The microprocessor Q106 isconstantlyoperating when the radio isturned ON. It iscontinuouslymonitoring the
keyboard, the PTT line and other internal inputs such as the squelch detect, etc. When a change occurs, the
microprocessor makes the appropriateresponse. The microprocessor is used for control. The Radio emits a beep on
channel change and the synthesizer is loaded with the correct frequency information. The microprocessor runs
off a 4.19304 MHz oscillator which is composed ofX101, C117, C118, and R135.
When the radiois first turned on,the microprocessor reads the radio status from the EEPROM Q109.
The microprocessor determines the receive frequency codes, then loads the synthesizer via its pins 17, 18 and 19.
3-2 VCO / SYNTHESIZER SECTION
This sectionconsists ofthe Temperature-Compensated Crystal Oscillator (TCXO), Voltage Controlled Oscillator
(VCO), Synthesizer and the Loop Filter.
Temperature-Compensated Crystal Oscillator (TCXO)
The reference oscillator(X301) is a temperature compensated crystal- oscillator, CV301 is used to adjust the oscillator
on frequency (21.25MHz) at room temperature (22°C). Q311, Q310, R314, R316, R319, R333, R334, R335 etc.
Temperature compensated is held within the specified 2.5 KHz from -20 to +50°C.
Voltage-Controlled Oscillators
The VCO of oscillates 446.00625 MHz to 446.09375 MHs under the transmission condition and 424.30625 MHz to
424.39375 MHz under the reception condition. The VCO consist of the clip oscillator of the Q305 and contaions the
oscillator frequency of approximately 21.7 MHz during the transmission/reception conversion. That is since the VCO
should oscillate relatively low frequency during reception compared to transmission, the Q307 is biased by the Q309.
Therefore as a result, the C312 is added in parallel to the resonance circuit of the VCO to oscillate a low frequency.
During transmission, a relatively high frequency should be oscillate compared to receprion. Therefore, the Q307 is
adversely biased by the Q309, and as a result, the C312 which is added unparalleled to the circuit of the VCO is
removed the desired transmission frequency.
Synthesizer
The PL synthesizer of the signal loop PLL circuit with the reference of 6.25 KHz. The Q303 PLL IC includeds all the
function such as the reference oscillator, the driver, the phase detector, the lock detector, and the programmable divider.
At the reference oscillator, the 21.25MHz TCXO is connected to the pin 1 of the Q303 to oscillate the frequency of
21.25 MHz. The TCXO (21.25 MHz) is the temperature compensation circuit to maintain the frequency within the
allowable error rang even under a low temperature of -20 . The phase detector send out the output power to the loop
filter through pin 14 of the Q303, If the oscillation frequency of the VCO is low compared to the reference frequency,
the phase detector send out output power in postive pulse. If the oscillation frequency of the VCO is high, phase
detector send out can maintain the frequency set. The progammable maintains the desired frequency with control from
the microprocessor Q106.
Loop Filter
The Loop Filter, a passive lead-lag filter consisting of C318-C320, R312, R313 and R317 integrates the charge pump
output to produce the DC turning voltage for the VCO. One parasitic pole, consisting of C318/R312 and RF choke
L305 prevent modulation of the VCO by the 6.25 KHz reference energy remaining at the output of the loop filter.
Direct FM is obtained for modulating frequencies outside the PLL bandwidthe by applying the CTCSS/DCS signals
and the pre-emphasized, limited microphone audio to the VCO modulation circuit.
The modulation circuit consists of Q315, C343, R309, R340and R341.

3-3 TRANSMITTER SECTION
RF POWER Amplifier
The transmitter parts of the TX-446 is designed to amplify the RF signal oscillated and modulated by the synthesizer to
approximately 500mW by the power transistor of Q407.
The transmitted signal of approximately 7mW, combined at the driver FET is supplied to the gate of the Q407 amplifier.
The transmitted signal amplifier to 500mW here passes the TX LPF of the second characteristics of the C418-C421, L408,
PCB_L1and PCB_L2and RX/TX switching takes place by the Q406. After this, the signal is provided to the antenna the
TX LPF of the first characteristics consisted of the C427,C428,C432,L412,L413 and L414.
Antenna Switching
Switching of the antenna between the transmitter and the receiver is accomplished by the antenna transmit/receive
switch consisting of diodes Q404 and Q406 inconjunction with C415 and R414. In the transmit mode, switched TX B+
is applied through RF choke L415, hard forward biasing the two diodes on. Q406 thus permits the flow of RF power
from output of the low-pass filter fed by the output amplifier to the output low-pass filter. Q404 shorts the receiver input
to C415, which is AC coupled to ground. L407, C416, C415 and R414 then function as a lumped constant quarter-wave
transmission line, thus presenting a high impedance to the RF output path, effectively isolating the receiver input and
transmitter output sections.
POWER Control
Output power iscontrolled by the microprocessor Q106, which is used as a differential amplifier and comparator.
Current is sensed by the voltage drop across R417.
When the radiotransmitter mode, this voltage is compared to the one set bythe 500mW.
The power output is then reduced or increased by varying the applied to the power amplifier Q407.
Transmitter Audio Circuits
The transmitter audiocircuits consist ofthe audioprocessingcircuits, the CTCSS circuits andthe DCS circuits.
Audio Processing
Transmitspeed audio is providing by either the internal electric microphone E201 or the external microphone.
The microphone audio ispre-emphasized by 6dB per octave by C540 and R557, and then signal amplification and
applied to Lo-pass filter Q507D,Q505D.
The gain is such that when a signal 20dB greater than limiting the peak-to-peak output.
Under these conditions, the MOD. ADJ. Pot RV501 configured as a four-pole active low-pass filter.
The resulting signal is then limited when respect toside band splatter, and has an 18dB per octave roll-off above 3KHz.
The audio is then applied to transmit VCO. By varyingthe voltage on the varactor diode Q308 at an audio rate.
The resonant frequency ofVCO is varied. The result is an oscillator output that is frequency-modulated at the audio
frequency.
CTCSS Tone Encoder / Digital Code Squelch (DCS) Encoder
CTCSS signals and DCS signals are synthesized by microprocessor Q106 and appear as pulse waveform on I/O lines
Pin 4-8. These I/O lines are applied toa resistive digital-to-analog converter network (consisting of R128-R132) which
produce a pseudo-sine wave for CTCSS or a waveform for DCS at itsoutput. The waveform issmoothed by low pass
filters Q507C to produce an acceptable sine wave output. The CTCSS tone signal is adjust to the proper level by
RV101. The DCS signal is adjust tothe proper balance by RV503. The signal is then applied tothe audio processing
circuit at R305 andto the TCXO circuit at X301.

The Receive VCO (C306, L302,R306,C308,C310, Q305,C311, L304) provides the LO signal. The VCO is running
at 21.7 MHz below the desired receive frequency and is applied to output Buffer Q301. The output of the buffer through
the low-pass filter C407, R406, L405 and applied to the mixer Q403.
Mixer
The mixer is a FET type (Q403). The mixer LO frequency is 21.7 MHz below the desired receiver frequency
When the receiver frequency is present, the mixer output will be a 21.7MHz signal. The mixer output is peaked for
21.7MHz at L406, C409, C410and the signal is filtered by crystal filter XF401 and XF402 and amplified by Q405
before being applied to the input of the IF IC Q503.
Inside Q503, the 21.7MHz IF signal becomes the input toa second mixer witha LO frequency of 21.258 MHz set by
X301. The 455kHz ceramic filter F501 filters the second mixer’s output which is the second IF signal.
The mixer’s output is then fed to the internal limiting amplifier and then on to the FM decoder.
FM Detector and Squelch
The FM detector output is used for squelch, decoding tones and audio output.
The setting of the squelch adjustment the microprocessor set the input to the squelch amplifier.
The squelch amplifier is internal to Q503 and itsoutput isfed to an internal rectifier and squelch detector.
The audio isunmuted by the microprocessor Q106 Pin 13 switching to a high (~5V) thus biasing on Q506.
The audio isthen routed to the audio amplifier Q702 via the volume control SW201B.
Receiver Audio Circuit
The detector’s audiooutputalso is fed to the tone (CTCSS andDCS) low-pass filter Q507A.
Then the output of the low-pass filter is routed to the second stage filter Q507B. The output of Q507B is applied to the
squaring circuitQ504D and finallytothe microprocessor Q106 Pin11 for decoding.
Another branchingofthe detectoroutputfeeds the audiohigh-pass filter Q504A, Q504BandQ504C. The output of the
audio high-pass filter feeds the Volume Control SW201B (VOL). From the wiper arm on the VolumeControl, the audio
is routed to Pin 4, the input to the audio power amplifier Q702. The output of the audio power amplifier isrouted through
the earphone jack J201 to the internal speaker E202.
3-5 BATTERY SECTION
The battery connects to the contact pins (CN203 and CN204) onthe bottomendofthe Radio.The positive terminal of
the battery connects to the ON/OFF Volume Control switch (SW201A)and the negative terminal connects to chassis
ground. Low battery sense R101/R102, voltage regulator Q208 andtransmit power amplifier Q407.
Battery voltage status is monitored by the microprocessor Q106 through R101/R102.
When the battery voltage is approximately 5.8V, the output is inputted into the Pin1 of the microprocessor Q101.
The battery voltage is below the preset value.
When the Radio is on a channel with no tone programmed, the BATTERY SAVER Mode is enabled when programmed.
In the BATTERY SAVER Mode, the microprocessor Q106 generates a square wave signal on Pin 21.
The signal's duty cycle varies according to what the POWER SAVE TIMER is set. When the microprocessor Q106 Pin21
goes high (approx. 5 V) Q205 is biased off, Q204B iscut off, Q203 is cut off, andQ204A iscut off, thus turning the
supply off to Q203.
Receiver Front End
In the receive mode, the RF signal enters thorough the antenna, then through the low-pass filter C427, C428, C430,
C432 and L412, L413, L414. The diodes Q404 and Q406 are biased off so that the output of the low-pass filter is,
coupled (C401) to the Front End RF overload protection diode pair Q401 and the first band-pass filter SAW401.
The signal from the band-pass filter is applied to the input of the RF amplifier Q402. The output of the RF amplifier
feeds the input to band-pass filter SAW402. The output from the band-pass filter is applied to the mixer's Q403.
