GH3000 Circuit Description 1.Introduction The model GH3000 is a 40 channel (2.40255-2.47595GHz) cordless telephone. The whole unit is divided into two main parts as follow : a. A remote Handset. b. A Base unit. 2.Functional Blocks of the Remote Handset 2.1 Keyboard matrix and function LED 2.2 MCU and MCU interface 2.3 Antenna and RF module 2.4 Compander 2.5 Data shaper 2.6 Charge detector 2.7 Low battery detector 2.8 Buzzer amplifier 3. Circuit Block Description 3.1 Keyboard matrix and function LED Pin 4 to pin7, pin 10 to pin 11 and pin 25 of the U2 MCU form a keyboard, and the talk LED is controlled by the pin 12 of the MCU. 3.2 MCU and MCU interface The handset and the base is link up by the pins(9,24 in HS and 21,24 in Base). Besides, the PLL of the RF Module is controlled by the pins 15,17 and 18 of the MCU. 3.3 Antenna and RF module ANT is the common point for transmitting and receiving through antenna. MD1 is a RF module which consists of Duplexer, Power amplifier, Mixer & IF, RXVCO, TXVCO, VCC & TXVCC control, Synthesizer and DEMO Audio Output circuits. 3.4 Compander A compander U3 is used for improving the S/N of the transmit and receive audio signal. 3.5 Data shaper The information which sending from base unit, is recovered by the amplifier Q1 and Q2. 3.6 Charge detector ZD1, D4, D5, D6, D7, D8, R53, C29 form a charge detector to direct the charging signal to the MCU pin 26. 3.7 Low battery detector A battery low detector is built-in by Q3 which detects the battery dropping and sends a signal to pin 19 of MCU. 3.8 Buzzer amplifier Q11 is a buzzer amplifier driven directly by the MCU pin 21,22 and 23. 4.Functional Blocks of the Base unit 4.1 Power supply 4.2 MCU and MCU interface 4.3 Antenna and RF module 4.4 Compander 4.5 Data shaper 4.6 Charge detector 4.7 Line audio interface 4.8 Ring detector 4.9 Led function board 4.10 Noise detector and carrier detector 5.Circuit Block Description 5.1 Power supply BQ4 8050 regulateS the input DC 9V to 5V which provides power to every part of the circuit. 5.2 MCU and MCU interface The heart of the base is BU5 MCU that communicates with the PLL of BMD1 through pins 5,6 and 7. Transmitter is controlled by the signal TX_DC which output from MCU via pin 20. MCU pins 6 to 11 consist of a resistor ladder for generating DTMF signal. The communication between Handset and Base is via the pin 24 and pin 26 through the RF link. 5.3 Antenna and RF modulator ANT is antenna transmit and receive signal. BMD1 is a RF modulator which consist of Duplexer, Power amplifier, Mixer & IF, RXVCO, TXVCO, VCC & TXVCC control, Synthesizer and DEMO Audio Output circuits. 5.4 Compander A compander BU1 is used for improving the S/N of the transmit and receive audio signal. 5.5 Data shaper The information which sending from handset unit, is recovered by the amplifier BQ1 and BQ2. 5.6 Charge detector BQ7 is a charge detector to direct the charging signal to the MCU pin 25. 5.7 Line audio interface BR20, BD9, BD10, BD11, BD12, BC40, BU5, BD13 and BTR1 line transformer are the audio interface to the telephone line. The transformer is also used for telephone isolation. 5.8 Ring detector BC41, BR11, BZD3, BZD2, BD8, BU4(K817P or LTV817) and BR44 form a ring detector which feed the signal through pin 26 of MCU. 5.9 LED function board BLED1 is used for indicating “IN USE” OR “CHARGING” when handset is on cradle. 5.10 Carrier detector The RF Module BMD1 pin 10 is an output pin of the carrier detector signal , it is sent to BU3 pin 23.When there is carrier, it is Low; when there is noise, it is High. BU5 finds the clear channel by this pin 23.
