1、Bluetooth Module Radio Architecture This section discusses the radio architecture for Class 2 designs. The first section covers the RF circuitry within the chip. Subsequent sections provide an overview of the external circuit design and Persistent Store (PS) Key configuration requirements. BLUETOOTH MODULE Transceiver 1.1.1 Transmitter Architecture The transmitter uses a conventional IQ modulator, as shows. The baseband Bluetooth signal is generated digitally and modulated in accordance with the Gaussian Frequency Shift Keying (GFSK) modulation scheme employed in Bluetooth. An additional frequency offset of up to ±1MHz can be added to the digital baseband signal. RF Performance Evaluation and Optimisation, discusses the reasons for adding a baseband transmit offset. Figure 1.1Figure 1.1: Overview of Transmitter Architecture 1.1.2 Receiver Architecture shows a receiver of a double conversion design, which uses the same synthesiser as the transmitter. The RF switch enables the use of inputs from either the differential or single-ended receive ports. The differential ports are the same TX_A and TX_B ports utilised by the transmitter. Single-ended inputs use the RF_IN port. Both differential and single-ended inputs are amplified by a low noise amplifier (LNA) and passed to an IQ mixer where the signal is then down-converted to a first intermediate frequency (IF) of 1.5MHz. This signal is amplified and filtered before undergoing a second quadrature mix to 2.5MHz. The 2.5MHz signal is further amplified and filtered. The signal is limited, sampled and then digitally demodulated. The 2.5MHz IF block also provides received signal strength indication (RSSI). Figure 1.2

FCC ID: V4H-SL8XX8 Page 2 of 8 TEST PROCEDURE GENERAL: This report shall NOT be reproduced except in full without the written approval of MOST TECHNOLOGY SERVICE CO., LTD. The EUT was transmitting a test signal during the testing. POWER LINE CONDUCTED INTERFERENCE: The test procedure used was ANSI Standard C63.4-2003 using a 50ｕH LISN. Both Lines were observed. The bandwidth of the receiver was 10kHz with an appropriate sweep speed. The ambient temperature of the EUT was 25 °C with a humidity of 58%. RADIATION INTERFERENCE: The test procedure used was ANSI Standard C63.4-2003 using a ANRITSU spectrum analyzer with a pre-selector. The analyzer was calibrated in dB above a micro volt at the output of the antenna. The resolution bandwidth was 100 kHz and the video bandwidth was 300 kHz up to 1 GHz and 1 MHz with a video BW of 3 MHz above 1 GHz. The ambient temperature of the EUT was 25 °C with a humidity of 58%. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was established by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor supplied by the antenna manufacturer and cable loss. The antenna correction factors and cable loss are stated in terms of dB. The gain of the Pre-selector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) METER READING + ACF + CABLE = FS 33 20 dBuV + 10.36 dB + 0.9 dB= 31.26 dBuV/m @ 3m ANSI STANDARD C63.4-2003 10.1.7 MEASUREMENT PROCEDURES: The EUT was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The EUT was placed in the center of the table (1.5m side). The table used for radiated measurements is capable of continuous rotation. The spectrum was scanned from 30 MHz to 10th harmonic of the fundamental. Peak readings were taken in three (3) orthogonal planes and the highest readings were converted to average readings based on the duration of "ON" time. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1m to 4m. The antenna was placed in both the horizontal and vertical planes. The situation was similar for the conducted measurement except that the table did not rotate. The EUT was setup as described in ANSI Standard C63.4-2003 10.1.7 with the EUT 40 cm from the vertical ground wall. Most Technology Service Co., Ltd.
