Waveguide Switches

Waveguide switches route microwave and millimeter-wave energy through waveguide interfaces where coaxial routing is not practical. They are used in radar, satellite ground systems, high-power test paths and waveguide distribution assemblies.

Waveguide switch for microwave path routing

FAQ

When should an electromechanical RF switch be used instead of a solid-state switch?

Electromechanical and solid-state switches occupy different loss, isolation, speed, power, size, control and lifetime boundaries; the route and switching sequence decide which is preferable.

How do insertion loss, isolation and crosstalk affect an RF switch route?

Insertion loss reduces the wanted path; isolation and crosstalk bound unwanted energy between named routes, so all three must be budgeted at the assembled matrix ports.

Which hot-switch, cold-switch and settling-time details belong in an RF switch RFQ?

An RFQ must separate carry power from power during transition and define the command, blanking, contact or logic change, RF settling, recovery and readback sequence.

Waveguide Switches

Waveguide switches change the path of RF energy inside rectangular or circular waveguide structures. They are used when frequency, power level or loss budget makes waveguide a better transmission medium than coaxial cable.

System role

These switches appear in radar transmit paths, satellite ground terminals, antenna feed networks, high-power microwave test benches and waveguide distribution systems.

Key data

Useful records include waveguide size or band, flange type, insertion loss, isolation, VSWR, peak and average power, actuation method, switching time, sealing and environmental rating.
