... The TH72006 evaluation board is designed to demonstrate the performance of the transmitter IC for conduc- tive measurements. The power amplifier is matched to 50 Ohms by means of a π-matching network to oper- ate at a resonant frequency of 315 MHz. The EVB72006 also features a clock output applicable to drive a microcontroller. The clock frequency can be selected by an external logic signal. 39012 72006 01 Rev ...
