IP65 sealed waveguide switches for Satcom ground stations

March 26, 2012

New from the Engineering Division of Link Microtek is a series of waveguide switches that offer environmental sealing to IP65 standard, enabling them to operate reliably even when subjected to dusty or moist environmental conditions.

Primarily aimed at automatic transfer applications in redundancy systems, the AM-WGS series switches are particularly suitable for use at civil or military satellite-communications ground stations. The devices are available in a wide range of rectangular waveguide sizes covering microwave frequencies from 2.6 to 40 GHz, typically for applications in the C, X, Ku and Ka-Bands.

Incorporating a small, lightweight motor, these electrically actuated switches offer tell-back functionality to confirm switch status and can also be operated manually in the event of a localised power failure. They can be specified with a 12 or 28 V operating voltage and a choice of connectors such as SMA, N-type and TNC. Optional features include choke flanges, pressurised waveguide sections, and failsafe or latching operation.

Designed and manufactured at Link Microtek's premises in Basingstoke, UK, the AM-WGS waveguide switches are fabricated from lightweight Alochromed aluminum and use an industry-standard footprint to ensure compatibility with other suppliers' products. In addition to the standard range, Link can supply bespoke designs to meet customers' specific requirements.
