7.8.2. Transmission line measurements
HP8753E VNA (Full-2-port calibration) has been used in this measurement session. A
calibrated coaxial cable has been soldered at the pad corresponding to RF output; a SMA
connector has been soldered to the board in order to characterize the losses of the transmission
line including the connector itself. During Return Loss / impedance measurements, the
transmission line has been terminated to 50 Ω load.
Return Loss plot of line under test is shown below:
