Digisat waveguide transfer switches route an RF path between two amplifiers, antennas or loads. They are the switching element in 1:1 and 1:N redundant uplink and downlink chains, and are built in sizes from WR28 (Ka-band) to WR340 (S-band) with a choice of flanges, drive voltages and control connectors.
Key features
- Sizes WR28 to WR340, Ka-band to S-band
- Low insertion loss and high isolation between ports
- Drive voltages from +/-12 VDC to 220 VAC
- Optional position-indicating C-form and inhibit contacts
- Choice of flanges and weather cap for outdoor mounting

Frequently asked questions
Which switch do I need for a redundant amplifier system?
Match the switch to the amplifier output flange (for example WR75 for Ku-band or WR137/WR229 for C-band) and to the drive voltage your redundancy controller supplies. Digisat can supply the complete redundant system, including the controller.
Need it installed, aligned or supported?
Digisat engineers install, commission and maintain satellite ground systems for government agencies, teleports and broadcasters worldwide. Request installation or engineering support.
