RadiSwitch | Coaxial Switch cards
The internal relays can’t be used for handling RF power that is higher than the maximum power specification. For applications that requires switching of a high-power RF amplifier, for example 5 kWatt @ 1 GHz, the RadiSwitch external switch card can be used. This plug-in card provides the DC power supply (selectable 12V, 24V or 28 V) and the driver current (maximum 500 mA per relay) for switching the external relay. Additionally, indicator contacts are available to determine the switching position of the external relay.
The RadiSwitch plug-in cards use high-quality RF relays with very low insertion loss and high isolation. The following maximum insertion loss and minimum isolation specifications (typical) are applicable for the different type of relays:
- BNC @ 1 GHz insertion loss: 0,15 dB / Isolation: 85 dB
- N-type @ 3 GHz insertion loss: 0,25 dB / Isolation: 75 dB
- SMA SPDT @ 8 GHz insertion loss: 0,20 dB / Isolation: 75 dB
- K-type SPDT @ 18 GHz insertion loss: 0,50 dB / Isolation: 60 dB
- Q-type SPDT @ 26.5 GHz insertion loss: 0,70 dB / Isolation: 55 dB
- V-type SPDT @ 67 GHz insertion loss: 1.10 dB / Isolation 50 dB
