FCC RF EXPOSURE COMPLIANCE
In August 1996 the Federal Communications Commission (FCC) of the United States with its action in 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 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:
z Reorient or relocate the receiving antenna
z Increase the separation distance between the equipment and the receiver

PLL loop is composed of single PLL synthesizer, Loop filter, VCO and VC-TCXO
It generates transmission and reception frequency of 9551372.08 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.

8. 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 : ± 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.

9. 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

RFT3100.
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.
