In order to control high-frequency signals, it is necessary to use dedicated
high-frequency relays rather than regular relays. The following problem
arise when relays are used in high-frequency circuits.
1. Leakage of signals between the contacts(circuits)when the contacts are open ⇒
The higher the frequency,the greater the leakage,and the greater the interference that
arises between circuits.
2. Loss of signals the contacts are closed ⇒ Insertion loss
The higher the frequency,the greater the signal loss between the contacts (circuits),
the less possible it becomes to transfer the signals reliably and the more this leads to heat generation.
Consequently, a relay that features minimal signal leakage between the contacts when the contacts are open and minimal signal loss when the contacts are closed even a higher signal frequency can be described as an excellent high-frequency relay.
