Keywords:PCB? Signal Board? power supply? TEA172x? RF transceiver?

The PCB structure as depicted in this application note contains two printed circuit boards: Horizontal: the Large Signal Board (LSB); and perpendicular in the middle of the LSB: to the Small Signal Board (SSB)

The LSB contains the resonant tank, the half-bridge driver (UBA20270), the input filter and some leaded components that could not be placed on the SSB.

The SSB contains the power supply (TEA172x) for the RF transceiver and, depending on SSB model, the supply for the half-bridge driver. The SSB is not mounted onto the LSB upon delivery so that customers can adapt the circuitry on the large LSB without requiring a remote control.
