Not recommended for new designs. The TH72036 evaluation board is designed to demonstrate the performance of the transmitter IC for conductive measurements. The power amplifier (PA) is matched to 50 Ohms by means of a π-matching network to operate at a resonant frequency of 868 and 915 MHz.

The EVB72036 also features a clock output applicable to drive a microcontroller. The clock frequency can be selected by an external logic signal.
