Frequency selection starts with the assembly
The useful operating range depends on the connectors, cable, transitions and installation. A series rating is not a test report for every part.
Read frequency ratings correctly
The catalog series references include SMA 18 GHz, 2.92mm 40 GHz, 2.4mm 50 GHz, 1.85mm 67 GHz and 1.0mm 110 GHz. Confirm the chosen model, launch and cable configuration.
Check more than maximum frequency
Specify VSWR or return loss, insertion loss, power and test conditions across your required band. Check temperature and mechanical installation requirements separately.
Ask for a reproducible measurement
Agree the reference planes, cable length, mating torque and calibration conditions. Ask which results apply to the exact model or assembly, rather than a different sample.
