The front panel and PCB for XtremeDx H7113R SDR
(not real scale)
4L PCB, The bottom layer
Top view, all layers
STM32 controller. Diff RF decoupled from 12VDC power supply. 7 ADC multiplexed inputs for DC U/I measurements as RFDSP voltage and current, PA voltage and current, VSWR voltages on VSWR bridge). Hole for one optical encoder. Holes for two mechanical rotary encoders - MULTI and ATT, one analog potentiometer for volume control on ADC. All inputs are RF and ESD protected. USART for communication with baseboard. (this architecture was tested in my H7R SDR)
