I need to make some measurements on PC boards up to 5 GHz using a network
analyzer. In the past I didn't care that much because I was doing TDR
measurements.

Unfortunately, the boards I will be looking at are too thick to use the "SMA
edge connector" trick.

Does anyone have a pointer to a good PCB footprint that will not have
impedance discontinuities. The connector I want to mount is the familiar
center pin + 4 ground pins vertical SMA style.

Thanks in advance for any help,

Larry Miller
