Introduction We have used the measurement procedures outlined in FCC Supplement C (Edition 97- 01) to OET Bulletin 65 [1] and an updated version of the same [2] for evaluating compliance of the RF Micro Devices Cardbus Card Model DK5405 (FCC ID# RFN5405RDK0401) inserted into Toshiba Model 1415-S173 Host Computer. Three photographs of the Toshiba Model 1415- S173 Host Computer with RF Micro Devices Cardbus Card Model DK5405 are given in Figs. 1a-c respectively. The RF Micro Devices Cardbus Card Model DK5405 uses two identical antennas that operate over the frequency band 5.18 to 5.32 GHz in the normal mode with conducted powers that are given in Table 1. For SAR measurements, two configurations of the wireless PC relative to the experimental phantom have been used. These are as follows: a. Configuration 1 is for the wireless PC placed on a user's lap. For this configuration, a planar phantom model with inside dimensions 12" × 16.5" (30.5 × 41.9 cm) and a base thickness of 2.0 ± 0.2 mm (recommended in [2]) was used for SAR measurements and the bottom side of the laptop computer shown in Fig. 1 was pressed against it (see Fig. 2). b. Configuration 2 – Edge-on position. This configuration corresponds to a bystandar close to the outer edge of the Cardbus Card. For this configuration, the PC is placed at 90º with the edge of the RF Micro Devices Model DK5405 Cardbus Card pressed against the bottom of the planar phantom. A photograph for this edge-on position for SAR testing is given in Fig. 3. 2 II. The SAR Measurement System The University of Utah SAR Measurement System has been described in peer-reviewed literature [3]. A photograph of the SAR Measurement System is given in Fig. 4. This SAR Measurement System uses a computer-controlled 3-D stepper motor system (Arrick Robotics MD-2A). A triaxial Narda Model 8021 E-field probe is used to determine the internal electric fields. The positioning repeatability of the stepper motor system moving the E-field probe is within ± 0.1 mm. Outputs from the three channels of the E-field probe are dc voltages, the sum of which is proportional to the square of the internal electric fields ( ) 2 i E from which the SAR can be obtained from the equation SAR = ( ) 2 i Eσρ, where σ and ρ are the conductivity and mass density of the tissue-simulant materials, respectively [4]. The dc voltages for the three channels of the E-field probe are read by three HP 34401A multimeters and sent to the computer via an HPIB interface. The setup is carefully grounded and shielded to reduce the noise due to the electromagnetic interference (EMI). A cutout in a wooden table allows placement of a plastic holder (shown in Fig. 5) on which the laptop computer with the 802.11a wireless antennas (see Fig. 1) is supported. The plastic holder (see Fig. 5) can be moved up or down so …
