Switch life
The life of a switch is usually specified in cycles, that is the number of times it switches from one position to another and back.
System 40 RF switches have lives from one-million to ten-million (1,000,000 to 10,000,000) cycles per switch position without
noticeable performance degradation.
NOTE
That is:
• No intermittent contacts
• Less than 0.1 dB increase in insertion loss
• Less than 0.3 ohm increase in DC contact resistance
