These two parameters are the most important for antenna performance. Reserve space around the antenna as much as possible. Connect all parts as close as possible to the pins of module and reduce the length of routing traces, to help on good audio performance, proper antenna pattern and EMC. When designing the receiver module in wireless speakers and headphones, the important design considerations are as follows:

1. Keep metal objects away from the antenna by 3 cm distance at least to avoid degradation on the antenna. For example, speaker unit, transformer, adaptor, wire, cable and other big metal object beside antenna will degrade the antenna performance. 2. Use regulated DC-power-supply to the modules, and separate the DC-power-supply of module with the other circuits. Antenna 1. Wire Antenna: A 27~31mm plastic-covered wire can be used as antenna. In principle, 31mm length is for a wire without any cover or very thin cover. The thicker of the cover, the shorter of the antenna length. Try various length for a certain wire to optimize the transmission distance. 2. Antenna Soldering:

RF signal between SOIC and antenna is separated to two paths: transmission and receiving (by two RF switches). Transmitted RF Signal from SOIC is following by a power amplifier to increase output power and transmission distance.

This equipment has been certified and found to comply with the limits regulated by the FCC 47 CFR part15, subpart A Section 15.21. You are cautioned that changes or modifications not expressly approved by the part responsible for compliance could void the users authority to operate the equipment. 2007.12.06 Version: 1.0 Page of 7 6 www.elansat.com

To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. This radio transmitter (identify the device by certification number, or model number if Category II) has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.
