Introduction
ITT Cannon’s Sealflex 2 microwave cable as-
semblies are designed for applications requiring
consistent microwave performance through to
18 GHz and may be used with minimal degradation
to 26 GHz, with SMA connectors.
All connector designs, except BNC, exhibit ‘mode
free’ characteristics to 18 GHz, thereby allowing
low VSWR to be specified without ‘spikes’ being
present in the upper frequency spectrum.
Each assembly is 100% tested for VSWR and
insertion loss and test plots are supplied with each
item.
Sealflex 2 assemblies have been adopted for use in
various avionic systems, missiles, military ground
and shipborne applications as well as commercial
communications equipment; in fact, anywhere
where cost effective high performance and
reliability is paramount.
