FCC Radiation Exposure Statement The available scientific evidence does not show that any health problems are associated with using low power wireless devices. There is no proof, however, that these low power wireless devices are absolutely safe. Low power Wireless devices emit low levels of radio frequency energy (RF) in the microwave range while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure to low level RF that does not produce heating effects causes no known adverse health effects. Some studies have suggested that some biological effects might occur, but such findings have not been confirmed by additional research. This device has been tested and found to comply with the Federal Communications Com…

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 May 29, 2003 RE: FCC ID: APYNAR0050_ATCB000471 Attention: Yoshiaki Iwasa / Yukari Ito I have a few comments on this Application. 1. Please note that the FCC ID number on the sample label does not match the ID number in the report, 731, confidentiality request and other application documents. The report states the FCC ID is APYNAR0050 while the FCC ID sample label state it is APRNAR0050. Please correct the application documents to have the same FCC ID number. Please advise as to the proper FCC ID number. 2. Please note that your conducted data tables are not accurate. They only show compliance to the QP limits. While a device is considered compliant if the QP is under the average limit, the margin must still be compared to that which yields the least margin. For example, in the conducted data table on page 17 of the report you incorrectly show only the QP limit being met. The AV limit is only compliant by 2.8dB. In lieu of actual averaged measurements, this QP reading compared to the average limit is the margin that needs to be reported. This applies to all of your conducted data tables. Please provide a report showing the least margin in accordance with the rules. 3. Please note that much of the information on the schematics did not come through. The pin designations, chip signal names etc are blank. Perhaps this is due to Asian fonts or some other non translatable problem. Please provide readable schematics. 4. Dennis Ward mailto:[email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination. Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued. Please do not respond to this correspondence using the email reply button. In order for your response to be processed expeditiously, you must submit your documents through the AmericanTCB.com website.

Calexico Single Band Card Theory of Operation Overview The Intel® PRO/Wireless LAN 2100 miniPCI adapter implements the 802. 11b physical (RF) specificati on. It operates at 1, 2, 5.5, and 11 Mbps. The Mini PCI card uses a Complementary code keying (CCK) baseband and SA2400 IC for modulation, demodulation, spreading and despreading of the RF signal. LAN 2100 The Intel® PRO/Wireless LAN 2100 miniPCI adapter implements the 82531ME, 802.11b CCK Baseband, and the Philips SA2400 radio ICs . 82531ME MAC Baseband OFDM processor CCK Baseband Processor Antennas MINI PCI Interface SA2400 2.4 GHz Radio Chip Tx, Rx Figure 1: Simplified Block Diagram for the Intel® PRO/Wireless LAN 2100 miniPCI adapter Transmit mode: The “upper” Media Access Control (MAC) logic inside the 82531ME is used to send and receive packets and transfers data to/from the host computer via the miniPCI interface. The 85231ME communicates with the CCK BBP IC through a special parallel interface called the Host Bus (H-BUS) interface. This i nterface uses registers with double-synchronizing flip-flops on all communica tion signals to prevent any ti ming-related problems between the two ICs. The CCK BBP IC functions as a “lower” MAC for the 80211b standard. This IC is also used to generate differential, analog I/Q vo ltage levels. The transmit I/Q signals are generated by 10 bit DACs (while the rece ive I/Q signals are read by 8 bit ADCs). These voltage level signals are first converted to current levels by external resistors networks and then are up-converted inside the SA2400 to the desired transmitt ing frequency. An integrated 4 th order low-pass Butterworth 9.75MHz filt er is used in the up-converter section fo r spectral shaping and reconstruction filterin g. Figure 1: Detailed Block Diagram for the Intel® PRO/Wireless LAN 2100 miniPCI adapter (Red items are on back side of PCB) 82531ME BBP MAC miniPCI SA2400 2.45GHz Direct Conversion Radio 40 MHz 22 MHz CCK BBP Differential I and Q MAX2242 RF PA 2.4-2.5GHz LOW PASS FILTER DP2T RF SWITCH 2.45GHz BANDPASS FILTER LNA 6dB PAD 6dB PAD 2.45GHz BANDPASS FILTER BALUN BALUN EEPROM ISOLATOR Rx Tx LOW PASS FILTER 1.8VA 1.8VD 3.3V 3.3VA 1.8VD 3.3V 2.9VA 3.3VA 3.3VA 3.3V 2.9VA J5 J6 Transmit mode (cont’d): The SA2400 generates a differential RF signal at the desired operat ing frequency. Please note, that since this is a zero-IF typ e design, there are no Intermediate Frequency (IF) stages used. The SA2400 beats the IQ modulation directly up to the appropriate frequency of ope ration set by its built-in PLL. Upon exiting from the SA2400, this differential signal is transformed to single ended form using a discrete balu n circuit. The balun is designed to convert 100ohm differential impedance to 50ohms single ended impedance while also supplying proper bias voltage to the output stage of the Philips IC. From the output of the balun, the signal is band pass filtered with a ceramic 2400 to 2500MHz Band Pas s filter (BPF). This filtered signal is then attenuated using a 6dB, 50ohm resi stive pi-attenuator network. A MAXIM 2242 chip scale RF Power am plifier (PA) IC is used to amplify the low level filtered compos ite signal to approximately +20dBm levels. At the output of the PA, a ceramic 2400 to 2500MHz Low Pass Filter (LPF) is used to reduce harmonic content in the amplified si gnal. From this point the signal is routed through the single band anten na diversity switch to one of the two U.FL antennae connector s. A discrete logic IC (not shown in the diagram) is used to decode antennae switching information from the CCK BBP IC in order to correctly operat e the antenna switch. This IC is a 74LVC08 IC on the back of the PCB. An RF signal level of approx -5dBm at the output of the SA2400 IC can be expected to produce an amplified RF signal of approxim ately +16dBm at the antennae connectors. Receive mode: During receive; the signal is first routed through a ceramic 24 00 to 2500MHz Band Pass filter (BPF) and through a single transi stor, Low Noise Amplifier (LNA). The amplified and filtered signal is then attenuated via a 6dB, 50ohm resistive pi-attenuator network. A 50ohm to 100ohm integrated balun is then used to convert the single ended signal to a differential voltage which can be applied to the receive terminals on the SA2400 IC. The LNA and attenuator form an isolation network which is requir ed to isolate the low level Voltage Controlled Oscillator (VCO) frequency leakage from the antennae. An isolation network helps to reduce DC offsets that occur when switching antennae in diversity application s. Inside the SA2400, the received signal is first amplified with an Automatic Gain Controlled (AGC) amplifier and then mixed down in frequency (from RF to DC) using a quadrature IQ up/down mixer. From her e the downconverted signal is then low-pass filtered using Chebych ev 5 th order active filters. A DC cancellation mechanism is able to reduce DC offsets by 70dB hence clipping of the baseband signals can be avoided. The baseband IQ signals are transmitted differentially via current signal which are converted to voltage by the external resist or networks. These differential analog IQ voltage levels are read by the 6 bit ADCs inside of the CCK BBP IC. The CCK BBP IC is used to demodulate the IQ signals to produce packets of data whic h is communicated to the 82531ME upper MAC a nd onwards to the host computer via the miniPCI bus. SA2400 Radio The SA2400 from Philips is a fully integrated single IC RF transc eiver designed for 2.4 GHz wireless LAN applications. It is a direct conversion radio architecture device and combines a low-noise aut omatic gain control (AGC) amplif ier, receive and transmit filt ers, and input/output buffers into a single IC. 82531ME MAC and Baseband The 82531ME chip incorporates Media Access Control (MAC) logic, baseband processing functions, and a miniPCI interface, as well as Analog-to-Digital and Digital-to-Analog conver ters (ADC and DAC). This fully integrated d…

The order requires routine SAR evaluation prior to equipment authorization of portable transmitter devices, including portable telephones. For consumer products, the applicable limit is 1.6 mW/g for an uncontrolled environment and 8.0 mW/g for an occupational/controlled environment as recommended by the ANSI/IEEE standard C95.1-1992. According to the Supplement C of OET Bulletin 65 “Evaluating Compliance with FCC Guide-lines for Human Exposure to Radio frequency Electromagnetic Fields", released on Jun 29, 2001 by the FCC, the device should be evaluated at maximum output power (radiated from the antenna) under “worst-case” conditions for normal or intended use, incorporating normal antenna operating positions, device peak performance frequencies and positions for maximum RF energy coupling. 1 Specific Absorption Rate (SAR) is a measure of the rate of energy absorption due to exposure to an RF transmitting source (wireless portable device). 2 IEEE/ANSI Std. C95.1-1992 limits are used to determine compliance with FCC ET Docket 93-62. SECTION 4 : Dosimetry assessment setup These measurements were performed with the automated near-field scanning system DASY3 from Schmid & Partner Engineering AG (SPEAG). The system is based on a high precision robot (working range greater than 0.9 m), which positions the probes with a positional repeatability of better than +/- 0.02 mm. Special E- and H-field probes have been developed for measurements close to material discontinuity, the sensors of which are directly loaded with a Schottky diode and connected via highly resistive lines to the data acquisition unit. The SAR measurements were conducted with the dosimetry probe ET3DV6, SN: 1684 (manufactured by SPEAG), designed in the classical triangular configuration and optimized for dosimetric evaluation. The probe has been calibrated according to the procedure described in [2] with accuracy of better than +/-10%. The spherical isotropy was evaluated with the procedure described in [3] and found to be better than +/-0.25 dB. The phantom used was the SAM Twin Phantom as described in FCC supplement C, IEE P1528 and CENELEC EN50361.
