CCT TELECOM R&D LIMITED U\..EX29638_circuit_description.doc Page - 2 - of 3 Circuit Description: Model: EX29638XXX-A Handset : 1. Receiving Path The receiving path is established by below sections. Low Noise Amplifier (LNA) FM signal is filtered by the SAW duplexer, and input to tuning amplifier Q4 before output to COMBO U1 1 st mixer. Mixer Mixer is included in COMBO U1. Local Oscillator (LO) is controlled through external coil L6. The first IF (10.7MHz) is filtered by a ceramic filter CF2. IF amplifier IF amplifier is built in U1. Amplified IF is filtered again by a ceramic filter CF1, then input to FM demodulator also inside COMBO. FM demodulator and expander The IF demodulated by quadrate coil COMBO, then the recovered audio is input to the expander for de-emphasis, before output to the handset speaker though audio amplifier. 2. Transmitting Path The transmitting path is established by below sections. Microphone amplifier and compressor Audio frequency picked up by handset microphone is amplified by internal mic amplifier of U1, then input to compressor for pre-emphasis, before input to the modulator. (TxVCO). Modulator and TxVCO The transmit VCO is internal at U1 and controlled by external coil L6. Both audio and data signal input to the transmit VCO will cause a frequency modulation progress. CCT TELECOM R&D LIMITED U\..EX29638_circuit_description.doc Page - 3 - of 3 RF power amplifier FM signal is amplifier by Q1 and fit to the antenna through SAW duplexer. Base unit 1. Receiving Path The receiving path is established by below sections. Low Noise Amplifier (LNA) FM signal is filtered by the SAW duplexer, and input to tuning amplifier Q27 before output to COMBO U2 1 st mixer. Mixer Mixer is included in COMBO U2. Local Oscillator (LO) is controlled through external coil L6. The first IF (10.7MHz) is filtered by a ceramic filter CF1. IF amplifier IF amplifier is built in U2. Amplified IF is filtered again by a ceramic filter CF2, then input to FM demodulator also inside COMBO. FM demodulator and expander The IF demodulated by quadrate coil COMBO, then the recovered audio is input to the expander for de-emphasis, before output to the final AF amplifier for line interfacing. 2. Transmitting Path The transmitting path is established by below sections. Mic amplifier and compressor Audio frequency input from the line interface is amplified by internal mic amplifier of U2, then input to compressor for pre-emphasis, before input to the modulator. (TxVCO). Modulator and TxVCO The transmit VCO is internal at U2 and controlled by external coil L6. Both audio and data signal input to the transmit VCO will cause a frequency modulation progress. CCT TELECOM R&D LIMITED U\..EX29638_circuit_description.doc Page - 4 - of 3 RF power amplifier FM signal is amplifier by Q26 and fit to the antenna through SAW duplexer. 3. Telephone line interface The telephone line interface circuit is established by below sections. Audio power amplifier TEA1062 of a speech IC is as power amplifiers, Line control Q2&Q10 is the opening for line seizure, which is controlled by Q3. Ring detect circuit U3 is used as a differential amplifier for accurately detecting the ring signal, which is connected by one 100nf capacitor C130 from the telephone line. U1 is used as ringer circuit with line DC powered, the speaker rings when there is an incoming call even no DC power supply connected 4, intercom circuit. the intercom circuit is established by below sections Q15 is used as a switch for TX which is controlled by the “int” signal. Q16 is used as a switch for RX which is also controlled by the “int” signal, Q14 is a pre-amplifier of RX audio signal. EX29638XXX-A digital security coding system: The handset and base unit of model EX29638xxx-A will exchange a randomly Generated 16-bit (total of 65536) discrete digital security code every time the “del/handshaking “ buttons of both base and handset are respectively pressed for seconds at the same time.
