Wireless Autani Transceiver (WAT2) Users Manual 5. 5. Antenna Antenna The WAT2 Module includes an integrated PCB trace antenna. The PCB antenna employs a meandering F-antenna design that is very compact and supports omni-directional signal radiation. To maximize the antenna efficiency an adequate ground should be provided on the base board. The position of the module on the base board and overall design of the product enclosure contributes to the antenna’s performance.

Wireless Autani Transceiver (WAT2) Users Manual 6.3 6. Dimensions Keep-out Area For maximum antenna performance hang the antenna keep-out area over the edge of the base board. Placing a ground plane on the layer directly beneath the WAT2 Module will allow you to run traces under this area. The WAT2 board can be placed on a base board without antenna overhang as long as all copper is kept away from the antenna keep-out area.
Wireless Autani Transceiver (WAT2) Users Manual 7. 7. Certifications Certifications 7.1 FCC – United State The WAT2 Module complies with Part 15 of the Federal Communications Commission rules and regulations. To continue compliance with Part 15 the end user MUST include a visible label on the outside of the final product which indicates the internal radio module is FCC approved. The exterior label can use wording such as: “Contains FCC ID: V8NWAT1000142”. To meet the section 15.
Wireless Autani Transceiver (WAT2) Users Manual 8. 8. Processing Processing !!WARNING!! The WAT2 Module contains extremely sensitive electronic circuitry. Handle board with proper ESD protection at all times. 8.1 Reflow Soldering A convection soldering oven is recommended. Preheat the assembly at a rate of 3oC/sec and stop at a final temperature of 150-200oC. Limit time above solder paste liquid temperatures to 20-40 seconds, do not exceed 260oC.
Wireless Autani Transceiver (WAT2) Users Manual 8.6 9. References Module Rework The WAT2 Module can be unsoldered from the base board. Take care not to overheat the module. Never attempt to rework the module itself, any such attempts will invalidate any manufactures warranty and potentially cause the module to violate FCC and IC specifications. 8.7 Alterations Any and all alterations to the WAT2 Module are highly discouraged and are completed at the consumer’s risk.
