VT9109 Circuit Description : The following circuit description for model VT9109 is base on the circuit diagram and block diagram of VT9109. VT9109 Handset : 1. Receiving Path The receiving path is established by below sections. Low Noise Amplifier (LNA) FM signal filtering by the duplexer , and input to tuning amplifier Q555. Then input to 2 nd tuning amplifier Q512 before output to mixer . Mixer Mixer is included Q520 , and local oscillator Q506 & Q504 , which is controlled by the PLL U1 PLL pin . The IF (10.7MHz) is filtering by a ceramic filter CF501 , the filtered IF will input to IF amplifier U1 pin 40. IF amplifier IF amplifier is built in U1. Amplified IF is filtering again by a ceramic filter F1 , the filtered IF will input to FM demodulator U1 pin 33. FM demodulator and expandor The IF is demodulate by quadrate coil T1 , then the recovered audio is input to the expandor for de-emphasis , before output to the handset speaker though audio amplifier . 2. Transmitting Path The transmitting path is established by below sections. Mic amplifier and compressor Audio pick up by handset microphone is amplified by internal mic amplifier of U1 , then input to compressor for pre-emphasis , before input to the modulator (Tx VCO). VTECH TELECOMMUNICATIONS LTD. FCC ID: EW789-5004-00 JOB #: 226AH0 EXHIBIT #: 6A Modulator and Tx VCO The transmit VCO is constructed by Q509 & Q503 , which is controlled by PLL of U1 . Both audio and data signal input to the transmit VCO will cause a frequency modulation progress. RF power amplifier FM signal is amplified by Q510 and fit to the antenna though duplexer .

The UUT was transmit- ting a test signal during the testing. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a prese- lector. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The resolution bandwidth was 100KHz and the video bandwidth was 300KHz up to 1.0GHz and 1.0MHz with a video BW of 3.0MHz above 1.0GHz. The ambient temperature of the UUT was 74.3oF with a humidity of 69%. APPLICANT: VTECH TELECOMMUNICATIONS LTD. FCC ID: EW789-5004-00 REPORT #: T:\CUS\V\VTECH\226AH0\226AH0.RPT PAGE #: 1 APPLICANT: VTECH TELECOMMUNICATIONS LTD. FCC ID: EW789-5004-00 TEST PROCEDURES CONTINUED FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was estab- lished by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor sup- plied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the Preselector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) METER READING + ACF = FS 33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m POWER LINE CONDUCTED INTERFERENCE: The procedure used was ANSI STAN- DARD C63.4-1992 using a 50uH LISN. Both lines were observed. The bandwidth of the spectrum analyzer was 10kHz with an appro- priate sweep speed. The ambient temperature of the UUT was 74.3oF with a humidity of 69%. ANSI STANDARD C63.4-1992 10.1.7 MEASUREMENT PROCEDURES: The UUT was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The UUT was placed in the center of the table (1.5m side). The table used for radiated measurements is capable of continuous rotation. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1m to 4m. The antenna was placed in both the horizontal and vertical planes. The situation was similar for the conducted measurement except that the table did not rotate. The EUT was setup as described in ANSIC63.4-1992 with the EUT 40 cm from the vertical ground wall.
