Start with the routing path

RF switch selection is clearer when topology comes before model numbers.

Routing need Start here Confirm next
One input to two paths SPDT interface, latching/failsafe, terminated option
Two paths switched together DPDT frequency class, pin style, system wiring
One path to multiple outputs SP3-6T / SP7-8T / SP10T port count, unused-port behavior, switch matrix layout

Note: insertion loss, isolation, power handling and control details are model-dependent. Submit the routing requirement for verification.

Frequently Asked Questions

How should I choose between SPDT, DPDT and multi-throw RF switches?

Start from the routing topology. Use SPDT for one input switched between two paths, DPDT for paired path switching, and SP3T to SP10T configurations when one signal path must be routed across multiple instruments, DUTs or test paths.

Should I select terminated or non-terminated RF coaxial switches?

Terminated switches can help control unused-port behavior in selected test setups. Non-terminated switches may be suitable for simpler routing paths. The choice should be reviewed against the signal path and measurement architecture.

Which connector interface is suitable for an RF coaxial switch?

Choose the interface by frequency range and mating system. SMA and N-type are common in many RF systems, while 2.92 mm, 2.4 mm and 1.85 mm interfaces are used for higher-frequency microwave paths when required.

What information is needed for RF switch matching?

Provide the switching topology, port count, connector interface, frequency range, terminated or non-terminated requirement, latching or failsafe mode, control voltage, pin style, RF power target and quantity.
