Hi,
I notice that the STHV series chips have T/R switch in it, but I wonder if the evaluation board can receive the echo signals? Then, if I want to develop a PCB board with STHV series chips, do I need to add a waveform generator before STHV chips? If I want to obatin the echo data, do I need to add ADC hardware module when receiving echo signals? Finally, some evaluation boards use FPGA and some don't, I don't know if there are any differences when don't using FPGA.
