Coaxial Switches

SPINNER supplies a wide range of switch types for the most demanding applications. Their RF power ratings range from a few watts to several hundred kilowatts, and they are available in sizes from N to 8 3/16″ and for frequencies up to 6 GHz.

SPINNER 2-way switches use a hypocycloidic gear. This technology makes it possible to combine an extremely compact switch drive and a very short switching time. A sophisticated mechanical design guarantees that the auxiliary contacts (e. g. for a carrier safety loop) are actuated before opening and after closing the RF contacts. Thus SPINNER switches reliably prevent accidental switching under load (‘hot switching’). Where ultra-fast switching times are essential, such as in radar systems, electronic switches with pin diodes are used.

SPINNER switches offer the following advantages:

Low insertion loss and high isolation
Low VSWR over the whole frequency range
Short switching times and high reliability
Long service life up to 2 mill. switching cycles for switches with mechanical drive
Almost unlimited service life for switches with pin diodes

When choosing HF switches, you rightly demand the highest level of material performance and reliability – and you can rely on the quality of SPINNER products.
