Not to be distributed or divulged without prior written agreement.   FCC RF EXPOSURE COMPLIANCE  In August 1996 the Federal Communications Commission (FCC) of the United States with its actionin Report and Order FCC 96-326 adopted an updated safety standard for human exposure to radio frequency (RF) electromagnetic energy emitted by FCC regulated transmitters. Those guidelinesare consistent with the safety standard previously set by both U.S. and international standardsbodies. The design of this phone complies with the FCC guidelines and these international standards. Use only the supplied or an approved antenna. Unauthorized antennas, modifications, or attachments could impair call quality, damage the phone, or result in violation of FCC regulations. This MM-5500U CDMA card has been tested for FCC RF exposure hand and body SARcompliance. In order to comply with FCC RF exposure requirements, this product must be operated with the MM-5500U CDMA card. The use of this card in any other type of host configuration may not comply with FCC RF exposure requirements and should be avoided. During operation, a 1.5cm separation distance should be maintained between the antenna,whether extended or retracted, and the user’s/bystander’s body (excluding hands, wrists,feet, and ankles) to ensure FCC RF exposure compliance.  CAUTION  Change or modification without the express consent of Maxon Electronics Australia Pty Ltd voids the user’s authority to use the equipment.  This equipment has been tested and found to complywith the limits pursuant to Part 15 of the FCC rules. These limits are designed to providereasonable protection against harmful interference in an appropriate installation. This equipmentgenerates, uses, and can radiate radio frequency energy and, if not used in accordance with instructions, can cause harmful radiation to radio communication. However, there is no guaranteethat interference will not occur in a particular installation. If the equipment does cause harmfulinterference in radio and television reception, which can be determined by turning the equipment on and off, the user is encouraged to try to correct the interference by one or more of the followingmeasures:   Reorient or relocate the receiving antenna   Increase the separation distance between the equipment and the receiver   Contact Maxon Electronics Australia Pty Ltd Technical Support for assistance.

Not to be distributed or divulged without prior written agreement.  7.  Description of frequency determining and stabilizing circuitry  Frequency synthesizing part is composed of the first local RX IF synthesizer which is single mode PLL synthesizer and the internal Tx IF and Rx IF synthesizer which are in RFT3100 and IFR3300 chip. These parts generate the first local oscillation frequency, Rx IF frequency and Tx IF frequency. -  First local frequency Synthesizer : 1372.08 MHz ~ 1419.54 MHz PLL loop is composed of single PLL synthesizer, Loop filter, VCO and VC-TCXO It generates transmission and reception frequency of 1372.08 MHz ~ 1419.54 MH -  Rx IF synthesizer : 367.2 MHz Rx IF PLL loop is consisted of PLL synthesizer in the PLL module, VCO built in IFR3300, loop filter and VC-TCXO(Crystal oscillator 19.2 MHz). It oscillates twice the intermediate receiving frequency of 367.2 MHz and then generates 183.6 MHz, Rx IF frequency. -  Tx IF Synthesizer : 267.2 MHz The configuration of PLL loop is composed of PLL Synthesizer, VCO which is internally installed, loop filter and VC-TCXO(19.2 MHz). It oscillates twice of the transmission intermediate frequency of 267.2 MHz and then generates Tx IF frequency of 138.6 MHz through the PLL loop. The frequency of 19.2 MHz generated from the VC-TCXO is the main clock of each the frequency synthesizer part. PLL frequency stability is determined by the stability of oscillator of VC-TCXO. This prevents maximum frequency variation from exceeding ±2.0PPM.

Description of circuit employed for suppression of spurious radiation  In the CDMA transmit signal path, the frequency spectrum at the output of the CDMA DACs contains unwanted frequency components due to the DAC output transition edges and transients. The transmit clock frequency and harmonics are found in the spectrum. Each CDMA DAC is followed by an anti-aliasing low-pass filter with a bandwidth of 630 KHz that reduces unwanted frequency components installed in MSM5500. And then Tx IF frequency from the RFT3100 is filtered by band-pass filter. The nominal specification of the filter is as following. -  Nominal center frequency : 138.6 MHz -  3 dB Bandwidth           : ± 630 kHz -  Stop band attenuation    :  40dB min. The Tx RF output of the Tx Mixer and the AGC amp is filtered again by the SAW band pass filter. The nominal specification of the filter is as follows. -  Pass band    : 824 MHz ~ 869 MHz -  Attenuation  :  DC ~ 800MHz        : 22 dB min.                    869 MHz ~ 1049 MHz : 25 dB min.                      1049 MHz ~ 2000 MHz : 19 dB min. Finally, the spurious generated from Power AMP is filtered by the duplexer. The nominal specification of the duplexer is as follows -  TX Pass band        : 824 MHz ~ 869 MHz -  Attenuation    : 869 MHz ~ 894 MHz : 40 dB min.

Not to be distributed or divulged without prior written agreement 9. Description of modulation system used  The MM-5500U CDMA card consists of MSM, baseband analog interface (RFT31000, IFR3300) as modulation system. The MSM integrates functions of a CDMA processing, a digital FM(DFM) processing, CDMA subsystem in the MSM performs CDMA signal processing about CDMA modulation / demodulation, viterbi coding/decoding, interleaving/de-interleaving, and etc.  The CDMA baseband processor performs forward-link demodulation, time tracking and reverse-link modulation for CDMA digital signals. The following figure shows a CDMA digital baseband processor block diagram.  Figure 9.1 CDMA digital Baseband Block Diagram  The modulator performs the orthogonal modulation, long code PN spreading and quadrature spreading. The resulting data stream is then band limited with FIR filters and sent to the analog baseband processor. The RFT3100 Transmit Signal Path (shown in figure 8-2) accepts analog I and Q data from the MSM and outputs modulated IF centered at 138.6 MHz to the RF transmitter. The RFT3100 transmit path outputs a differential IF signal with spread spectrum modulation expending ±630KHz from the transmit IF center frequency of 138.6 MHz. The analog I and Q baseband components from the CDMA low-pass filters are mixed in quadrature with unmodulated I and Q signals at 138.6 MHz. After mixing, the I and Q IF components are summed and output differentially. The 138.6 MHz I and Q IF VCO signals are generated on the RFT3100.

Not to be distributed or divulged without prior written agreement The transmitter IF VCO is set to 267.2 MHz by an external varactor-tuned resonant tank circuit. An internal phase-lock loop and external loop filter network provides the feedback to the varactor that tune the VCO precisely to 267.2 MHz. A master-slave divide-by-two circuit generates I and Q signals in precise quadrature for the mixers.
