General Description The TH72016 evaluation board is designed to demonstrate the performance of the transmitter IC for conductive measurements. The power amplifier is matched to 50 Ohms by means of a -matching network to operate at a resonant frequency of 433 MHz. The EVB72016 also features a clock output applicable to drive a microcontroller. The clock frequency can be selected by an external logic signal.
