FIG. 2 The demodulated signal, resulting from Double Super Heterodyne system, which appears at output Pin no.3 of J 3 is sent to U2 (COMPANDER IC) Pin no.16 for Expansion. The expended audio signal output from Pin no.19 is coupled to Q1,Q3 during the TEL. mode The audio signal is sent to the Telephone Line via Q3. The demodulated data code from J3 Pin no.3 is Generated by U5-C, U5-B. It’s output is connected to CODE Input Pin no.14 of IC3. The Audio signal receiving from TEL-LINE is input to U2 Pin no.8 for compression. The compressed audio signal from Pin no.1 of U2 is connected to Pin no.10 of J3 for TX modulation. RF MODULE AF-IN VCO BPF4 5.8GHz TX ANTENNA PLL IC IC2 Q5,7,10 TCXO 11.15MHz TREMMER CAP. VC1 Pin no.31 of IC3 is the output port for data codes that should be transmitted to the handset the data code is connected to Pin no.10 of J3 for modulation. Line controlling is done by Pin no.18 of IC3. Ring signal monitored by U5-A is detected by Pin no.16 of IC3 resulting a data code to the handset. DTMF dialing is generated by IC3 Pin no.20~25 this signal output through the U5-D. When the handset is placed on the base cradle, the charging is detected by Pin no.13 of IC3 and IC3 sends data codes to handset for security code setting. When the handset is far away form base unit, squelch circuit of RF module operates and Pin no. 5 of IC3 goes “HI”. This will be detected by the micro processor and after 20 sec. go to Stand by mode. The power to the base unit is supplied by U3(5V REGULATOR IC). LED display control Pin no.9 of IC3.
