Latching Waveguide Switches
Latching Waveguide Switches allow engineers to switch reliably between two RF channels. The latching type stays stable in both positions without holding current. You can choose manual or automatic (electromagnetic)…
With over 70 years of RF experience, EVERAXIS specializes in designing the most demanding Waveguide Switches in extremely complex systems, including in low quantities.
EVERAXIS offers market leading solutions for passive microwave components, integrated waveguide assemblies, Rotary Joints and Rotating Subsystems for both the military and civilian radar and satcom markets.
What is a Waveguide Switch ?
A Waveguide Switch is an electromechanical or manual relay for RF signals. The most common type of RF switches consists of DPDT (Double Pole Double Throw) both failsafe and latching, with or without position indicators.
Waveguide Switches have a square stator with four waveguide ports. The rotor, which is fitted in the stator, has two or three channels. Electrical continuity between rotor and stator is achieved by means of quarter wave chokes. These chokes provide extremely high isolation between the channels while ensuring unchanged high electrical performance throughout the lifetime of the switch.
EVERAXIS Mechanical Waveguide Switches provide high isolation, low insertion loss, high power capability and a long life. For all latching models, the current is automatically switched off when the rotor is in position. One or several sets of position indicators are available with all models of actuators. Some models can be supplied with a manual override knob for manual position setting.
What are Waveguide Switches used for ?
EVERAXIS Waveguide Switches are widely used in microwave systems:
• In radars for redundancy transmitters
• In radars for connection to high power dummy load
• In radars for test purposes
• In satellite communications for redundancy applications
• In test systems to select various signal paths, etc.
