Hello,I have a differential line connected by 4 ports using 1.85 sma connectors.
one differential port on one side and another differential port on the other side.the PCB is placed in an oven ,I expect the temprature cause S21 to be more lossy but instead its getting less lossy.
As shown in the photo.Why is it happening?
What could be done to make the insertion loss getting bigger with temprature?
Thanks.
