ATTACHMENT
The antenna pads are designed to support both hand and automated
placement. Castellations have been provided to ease solder introduction
during hand assembly. The parts are also fully compatible with the reflow
process for automated assembly.
APPLICATION CONSIDERATIONS
When implemented correctly the “Splatch” will yield outstanding and repeat-
able results. However, the “Splatch” was designed with very specific feed and
mounting requirements. Failure by the designer to respect these require-
ments will result in unsatisfactory performance.
* The antenna is tuned for direct mounting to a product’s PCB. Mounting the
antenna in any other manner will produce poor results.
* The antenna should be fed with a trace <=.25". Longer runs or coax feeds
are not recommended.
* Nothing should be placed under or directly beside the antenna element.
Generally, mounting the antenna at the front of a product as illustrated will
yield the best results.
