RF Switches

Manifold switching operations in transmitting and receiving stations for mobile communication, broadcasting, radar and satellite systems as well as medical devices are executed by changeover switches, 2-way switches (transfer switches) or step switches with electrically controlled or manual operation.

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 you select rf switches you are right to demand the maximum material performance and reliability – and to trust in the quality of SPINNER products
