I have designed reflectometer circuit using high directivity couplers.
In context of AD8302, the typical slope mentioned in the datasheet is 30mV/dB. However at the same frequency of operation, it changes with chip to chip.
I wanted to know if anyway we can find the exact slope using measured reference voltage of AD8302. Please note that the OPEN, SHORT and 50ohm termination mVolts are available.
My ultimate aim is to bring my designed reflectometer PCBs to the same platform in order to achieve same response from all PCBs.
