Transmission Line Measurements
An 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 terminat
ed to 50 Ω load.
Return Loss plot of line under test is shown below:
Line input
impedance (in Smith Chart format, once the line has been terminated to 50 Ω
load) is shown in the following figure:
