MEDIUM POWER & SLIDING TERMINATIONS
Low VSWR
Adjustable phase
Description
80-LS Sliding Terminations consist of a
well-matched, tapered sliding load in a precision aluminum waveguide housing. The load can
be moved over more than one half wavelength at the lowest frequency. Optional micrometer
drive is available for bands H through A. Applications include simulating a perfect
termination for precise measurement of VSWR, impedance, directivity pr isolation. By
receiving the phase of the sliding termination it is possible to subtract it from other
small reflections in the system under test.
80-M Medium Power Terminations are convection-cooled
and similar to the low power series, but designed to handle higher power levels. Feature
include low VSWR and light weight. Typical applications include system or test bench
set-ups and as moderate power dummy loads.
Both series are available with optional sampling
probes supplied as separate units from 30 to 50 dB with typical flatness of ± 0.5dB.
Finish is Chemical Film, per MIL-C-5541, Class 3, followed by gray epoxy enamel for
sliding loads and black enamel for medium power terminations.
