TARCCU-550CDMA WIRELESS USB MODEM

CCU-550 Modem User Guide 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 modem 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 modem, or result in violation of FCC regulations. This CDMA 1xEVDO USB data modem has been tested for FCC RF exposure hand and body SAR compliance with the CCU-550 USB dongle modem form factor. In order to comply with FCC RF exposure requirements, the CDMA 1xEVDO USB data modem must be operated with the CCU-550 USB dongle modem 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.

Fig 5.2 RF part block diagram 1.3.1.1 Frequency synthesizing part Frequency synthesizing part called PLL Synthesizer consists of three synthesizer circuit which is first local synthesizer, Tx IF synthesizer and Rx IF synthesizer. The first local synthesizer generates the primary local system oscillation frequency, operating over 1372.08 ~ 1419.54 MHz frequency range. Tx IF and Rx IF synthesizer generate the second local oscillation frequency, 267.2 MHz and 367.2 MHz respectively. 1.3.1.2 Receiving part - Duplexer. The duplexer filters the RF signal transmitted through Antenna and sends the signals to LNA. - LNA. This part in front-end is used to amplify the received signal with low noise figure - Down converter. It acts as a mixer using first local frequency to produce the desired signal in the mid-range frequency of 183.6 MHz. - Rx AGC. This part is designed to control the gain of the dynamic range of midrange frequency produced in down converter according 80 dB dynamic range. Currently, previous BBA is divided into S1M8662(Rx IF-baseband converter) and RFT3100 (Tx baseband-IF converter). S1M8662 acts as the baseband analog processor which processing the signals between the S1M8662 and digital processing circuit. In the while, RFT3100 consists of Tx AGC and Tx part analog processor of previous BBA. 1.3.1.3 Transmission part - Tx AGC. It is designed to be gain-controlled from 84 dB dynamic range. The gain of this part is controlled by MSM using digital control signal. - Up converter. This part mixes the IF transmission frequency 138.6 MHz and the first local 1372.08 ~ 1419.54 MHz to generate transmission frequency of 824.64 ~ 848.37 MHz. - Power AMP module. This part is designed to work in 824 MHz ~ 849 MHz frequency range in the CDMA mode and can generate the proper output power. The DC voltage into the power amp module is typical 3.8V.

INTRODUCTION The measurement procedure described in American National Standard for Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9kHz to 40GHz (ANSI C63.4-2003) was used in determining radiated and conducted emissions emanating from CMOTech Co., Ltd. FCC ID : TARCCU-550 These measurement tests were conducted at Nemko Korea Co., Ltd. The site address is 300-2, Osan-Ri, Mohyun-Myun, Yongin-City, GyungGi-Do, KOREA The area of Nemko Korea Corporation Ltd. Test Site is located in a mountain area at 80 kilometers (48 miles) southeast and Incheon International Airport (Incheon Airport), 30 kilometers (18miles) south-southeast from central Seoul. It is located in the valley surrounded by mountains in all directions where ambient radio signal conditions are quiet and a favorable area to measure the radio frequency interference on open field test site for the computing and ISM devices manufactures. The detailed description of the measurement facility was found to be in compliance with the requirements of §2.948 according to ANSI C63.4 2003. Fig. 1.
