Those guidelines are consistent with the safety standard previously set by both U.S. and international standards bodies. 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 CDMA PCMCIA Card has been tested for FCC RF exposure hand and body SAR compliance with the MM-5100P PCMCIA Card form factor. In order to comply with FCC RF exposure requirements, the CDMA PCMCIA Card module must be operated with the MM-5100P PCMCIA Card form factor. The use of this device 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 comply with the limits pursuant to Part 15.105 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in an appropriate installation. This equipment generates, 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 guarantee that interference will not occur in a particular installation. If the equipment does cause harmful interference 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 following measures: Reorient or relocate the receiving antenna Increase the separation distance between the equipment and the receiver Contact Maxon Electronics Australia Pty.

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 MSM5100. And then Tx IF frequency from the RFT3100 is filtered by bandpass filter. The nominal specification of the filter is as following. Nominal center frequency : 138.6 MHz 3 dB Bandwidth Stop band attenuation : ± 630 kHz : 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. 23/25 Maxon Proprietary : Restricted Distribution. Australia.

Description of modulation system used The CM-5100P 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 8-1 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 24/25 Maxon Proprietary : Restricted Distribution. Australia.

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.
