LIONDA TECHNOLOGY COMPANY LIMITED ENGINEERING DEPARTMENT MH9110desc Page 1 2/22/2002 CIRCUIT DESCRIPTION Model: MH9110,MH9111 Base a. RF Transmitter Section – RF Board Compressed audio signal is frequency modulated through the varactor diode D3, D4. Diode D3, D4, L4 and Q5 the external components formed the voltage controlled oscillator circuit for the transmitter part. This circuit generates the TX VCO frequency. A portion of this signal is fed back to the PLL IC’s pin1 (FIN1) for phase comparison. Once the phase of oscillation stabilized, the PLL circuit generates the error voltage necessary for the VCO to oscillate at the desired transmitter’s RF frequency. The VCO circuit impedance is matched with the succeeding circuit through the transistor Q2 that also acts as the buffer amplifier. RF amplifier Q7 boosts the signal for transmission. This amplified RF signal is trimmed to the desired frequency band by BPF2403 so as not to interfere with the receiver circuit. The transmitter RF signal is then propagated through the antenna. b. RF Receiver Section - RF Board The Base Unit antenna receives RF signal. Band Pass Filter BPF903 trims the signal to the desirable frequency band. Transistor Q6 & Q3 is a low noise amplifier that boosts the RF signal to a specific level for mixing. PLL IC1 (KB8825B) is used as a Universal Phase Lock Loop circuit. The frequency from the Voltage Controlled Oscillator (VCO) D1, L5 and Q4, is fed back to the PLL IC through pin 16 (FIN2) for phase comparison. During channel scanning or turning the unit on, once the phase of oscillation stabilized (locked), the PLL circuit generates the first local oscillator frequency for down-converting the received RF signal into the first IF frequency 10.7MHz. This process is accomplished through the IF mixer circuit Q1. Q1 is used for matching the impedance of the mixer circuit with the succeeding circuits. The resulting IF signal is kept constant by the IF Filter FL1 to 10.7MHz which is then mixed with the second local oscillator frequency 11.150MHz (derived from X1 & C47) to produced a much lower IF frequency. This lower IF frequency if further filtered by IF Filter FL4 to produce a more stable signal of 450AKHz. Quadrature signal detection is accomplished internally by the Narrow-band Detector IC2 (KA3361) with the IF coil L7. The recovered audio frequency can be taken from IC2 audio output pin9. Double conversion of received signal is utilized to improve the image frequency rejection of the unit. c. Transmitter Audio Section – Main Board 1 LIONDA TECHNOLOGY COMPANY LIMITED ENGINEERING DEPARTMENT MH9110desc Page 2 2/22/2002 Audio Frequency signal from the telephone line is compressed through the compressor part of IC4 to minimize the transmission noise. The degree of compression depends on the external RC combinations. AGC is also utilized by IC4 to avoid shock noise caused by abrupt change of audio levels. The compressed audio is filtered and amplified for better acoustical performance. d. Receiver Audio Section – Main Board The compressed Audio Frequency signal is passed through passive RC filters for acoustic compliance. The filtered audio is then fed to the Compander IC4 for expansion thus retrieving the original Audio signal with noise filtered out. Q5 is used as buffer circuit. Bridge rectifier D12-D15 isolates the high-voltage telephone line to the rest of the circuit. D12-D15 is also act as a hybrid transformer to create a two-way path for audio transmission to and reception from the telephone line. Handset a. RF Transmitter Section – RF Board Refer to portion 1.b for this section. All circuit performance is the same except that Band Pass Filter BPF927 is changed to BPF903 for the handset transmission. b. RF Receiver Section – RF Board Refer to portion 1.b for this section. All circuit performance is the same except that Band Pass Filter BPF903 is changed to BPF927 for the handset reception. c. Transmitter Audio Section – Main Board Audio Frequency signal from the handset or from the headset microphone is compressed through the compressor part of IC1 to minimize the transmission noise. The degree of compression depends on the external RC combinations. AGC is also utilized by IC1 to avoid shock noise caused by abrupt change of audio levels. The compressed audio is filtered and amplified for better acoustical performance. Q3 is a switching transistor that controls the power supply for the TX RF part. d. Receiver Audio Section – Main Board The compressed Audio Frequency signal is passed through passive RC filters for acoustic compliance. The filtered audio is then fed to the Compander IC1 for expansion thus retrieving the original audio signal with noise filtered out. Q2 & Q10 act as audio amplifier to sufficiently drive the handset speaker. Q7 and Q8 are 2 2 LIONDA TECHNOLOGY COMPANY LIMITED ENGINEERING DEPARTMENT MH9110desc Page 3 2/22/2002 switching transistors that control the power supply for the RF part, the Compander part and the AF amplifier respectively. An earphone jack is provided for an optional headset unit for handsfree conversation on the handset. OTHERS (Handset): a. Charging and Reset Controls Recharging the handset battery is accomplished by putting the handset on the cradle. IC5 detects this action and sends a command to the CPU for proper exchange of security code. b. Ring Detection When the handset receives the ring command from the base unit, the CPU will send buzzer signal to the ringer amplifier Q5 and Q6 that drives the Buzzer. OTHERS (Base): a. Hook Switching and Dialing Hook switching and the transistor Q6 that is controlled by the CPU accomplishes pulse dialing. DTMF signal from the ladder circuit internal to the CPU is filtered and amplified by Q5. b. Over-voltage Protection Fuse1 and varistor Z1 act as high current and high voltage protectors for the telephone line interface. In case of presence of voltage surge across the telephone line, Fuse1 decreases its resistance and dumps the line vo…
