Walsin Technology Corporation Page 5 of 8 ASC_ANT7635110A1T_V06 Dec.-2004 RADIATION PATTERN Radiation Pattern and Gain were dependent on measurement board design. Walsin’s LTCC chip antenna is an electrically small antenna (size smaller than 1/10l). The specification of RFANT7635110A1x series chip antenna was measured based on the PCB size and installation position as shown in the below figure Test Board Return Loss (S11) E-Plane (dBi) H-Plane (dBi) The typical tuning range of Walsin’s chip antenna is about ±150MHz. The performance of embedded ceramic antenna is sensitive influenced by customer's ground area, PC board size, thickness, material, mechanical design and the material of housing for end product. WTC engineers have significant expertise on embedded antenna designs and applications. We can work closely with you to ensure the requirements are met, and optimise the WTC’s antenna performance when installing on your application.

Compliance with 47 CFR 15.247(i) “Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission's guidelines. See § 1.1307(b)(1) of this chapter.” The EUT is a 2.4GHz transmitter installed in the Rocket Fish M/N RF-WHTIB wireless rear-channel speaker extender. The EUT will only be used with a separation distance of 20 centimeters or greater between the antenna and the body of the user or nearby persons and can therefore be considered a mobile transmitter per 47 CFR 2.1091(b). The EUT has two antenna ports; both ports use the same antenna model. The max gain of the antenna is +2dBi. The maximum peak conducted output power is 7.9mW. The maximum peak power is 12.52 mW (EIRP) for FCC ID: UQ5RFWHTIBREC. The transmit frequency is in the 2400-2483.5MHz frequency range. The EUT is not subject to routine environmental evaluation per 47 CFR 2.1091. Per 47 CFR 1.1310, the EUT must meet the General Population/ Uncontrolled exposure limits listed in Table 1. The MPE estimates are as follows: Table 1 in 47 CFR 1.1310 defines the maximum permissible exposure (MPE) for the general population as (f MHz /1500) mW/cm 2 . The exposure level at a 20 cm distance from the EUT’s transmitting antenna is calculated using the general equation: S = (PG)/4πR 2 Where: S = power density (mW/cm 2 ) P = power input to the antenna (mW) G = numeric power gain relative to an isotropic radiator R = distance to the center of the radiation of the antenna (20 cm = limit for MPE estimates) PG = EIRP Solving for S, the maximum power density 20 cm from the transmitting antenna is summarized in the following table: MPE Estimate Antenna Type Antenna Manufacturer Antenna Part No. Transmit Frequency Max Peak Conducted Output Power Antenna Gain Minimum Antenna Cable Loss Power Density @ 20 cm General Population Exposure Limit from 1.1310 (MHz)(mW)(dBi)(dB) (mW/cm 2 )(mW/cm 2 ) Multilayer Ceramic Chip Walsin Technology Corporation RFANT763511 0A1T 24007.9200.0021 FCC ID: UQ5RFWHTIBREC The power density does not exceed 1.0 mW/cm 2 at 20 cm; therefore, the exposure condition is compliant with FCC rules. The applicant’s radio, FCC ID: UQ5RFWHTIBREC, is compliant with the requirements of 15.247(i).
