4 PCB Layout Requirements

Since this module and its associated set of approved antennas has been certified by the FCC

and Industry Canada (IC) as a Modular Radio, the end user is authorized to integrate this

module into an end-product, and is solely responsible for the Unintentional Emissions levels

produced by the end-product.

In order to preserve the Modular Radio certifications, the integrator of the module must abide by

the PCB layout recommendations outlined in the following paragraphs. Any divergence from

these recommendations will invalidate the modular radio certifications and require the integrator

to re-certify the module and/or end-product.

The module must be used with one of the approved antennas:

1. Johanson Technology 2450AT18A100 Ceramic Chip Antenna.

2. LSR 001-0001 center-fed 2.4 GHz dipole antenna and 080-0001 U.FL to Reverse Polarity

SMA connector cable.

3. LSR 001-0014 2.4 GHz FlexPIFA Antenna w/U.FL cable.

The module must be follow one of two trace antenna designs. The primary trace antenna

design is based on a 4-Layer PCB, and the secondary trace antenna design is based on a 2-

Layer PCB. Both trace antenna design CAD packages, which consist of the schematics, Bill of

Materials (BOM), and PCB Layout are available from LSR.

Please use the latest CAD files from the LSR web site when incorporating the TiWi-C-W module

into a new design. CAD files are provided in native Mentor Grahics PADS PCB and PADS

Logic formats, as well as ASCII, Gerber, and PDF formats. CAD files can also be translated to

most popular CAD package. Contact LSR Tech support for CAD translation.
