Any adapters beyond this point are included in the measurements. (Sample setup of adapters, actual setup not depicted.) VNA Adaption for 75 ohm Testing: In order to use the Agilent E5071C VNA for 75 ohm testing, we utilize Agilent minimum loss pads, PN 11852B. These matching pads are only rated to 3 GHz and as such, the data above 3 GHz is for reference only. There is a notable amount of ringing in the Insertion Loss curves for all samples above 3 GHz and again above roughly 5.5 - 6 GHz caused by this limitation. Adapter Use: Each port uses at least one precision adapter capable of mating to the assembly under test. Any supplementary adapter will contribute additional electrical characteristics to the measured data. Any use of additional adapters is noted. Definition of Assembly under Test: The performance characteristics include the interface with adapters. Port Designations: The connector attached to port 1 of the VNA is “End 1” from the part number callout. Insertion Loss is measured using S21 and Return Loss / VSWR is measured using S11. Legend for Plots: 5 samples were tested. Only the min/max plots are presented for clarity in this report.
