Thanks Pragash. Soldering a UFL connector is good idea but it also introduces loss in the system. Do you have any suggestion for a connector that would not introduce any loss in the system.
On my PCB I have ground-signal-ground RF pads on one side while I have SMA connector mounted on other side. Basically, I want to estimate path loss from the SMA connector (on one side) to RF pad signal(on other side).
How can I measure this with VNA, without soldering anything on the RF pad.
