The frequency of the ADSL signal is higher than that of voice, so voice and ADSL signal can coexist in one line by using a splitter to insulate each from the other. ADSL data transfer adapts the asymmetry model. It supports upload transmission speed up to 1Mbps and download speed up to 8 Mbps (24Mbps for ADSL2+). ADSL is an ideal device for broadband access. 1.2 ABOUT ADSL2/2+ Transmission performance of ADSL2 is improved comparing with the first generation of ADSL. These improvements are mainly concerned with long distance, anti-line-loss, anti-noise, etc. By doubling the transmission bandwidth, ADSL2+ has implemented a downlink rate as high as 24 Mbps. Therefore, Internet applications such as synchronous transmission of multi video stream, online games and huge capacity of download…

Circuit Description a. Transmitter section Data from the host is sent to the U6(BCM4318) through the RF_OUT interface. After being converted from digital to analog signals by the I and Q transmit digital-to-analog converters (DAC) in the U6(BCM4318) the output signals are routed to the Transceiver SIGE2521A60 (U17) . Antenna1 connect to SIGEI-PLEX connector. b. Receiver section The input signal to the radio is received through either antenna1 or antenna2. The received signal from the selected antenna connect to SIGE2521A60.Which is fed to a bandpass filter. Then, the signal is routed to multilayer balun(U15:HHM1520). After the U15(HHM1520) the signal output to BCM4318 , which the signals direct ADC to BCM6338. c. RF VCO section The RF VCO(2.412-2.484Ghz)(BCM4318) operates at twice the channel frequency. It is divided by two in a flip-flop circuit to form accurate in-phase (I) and quadrature (Q) LO signals at the channel frequency. The VCO is phase locked to the 20MHz crystal-controlled clock by the synthesizer in the U6 (transceiver BCM4318) and therefore constitutes an accurate channel frequency reference for the radio.

Both are below the uncontrolled exposure limit of 1.0 mW/cm 2 at 2437 MHz. The EUT is used at least 20 cm away from user’s body. It is determined as mobile equipment and complies with the MPE limit.
