The major advantages of waveguide filters are high power handling and low-loss performance. Waveguide filters are fabricated in aluminum, brass, copper and Invar. Materials are selected to ensure that the lowest possible passband insertion losses are achieved. The advantage of Invar construction is its low thermal expansion, which provides optimum temperature stability. Aluminum construction is best suited where weight is of major importance. All filters have tuning screws that are locked and sealed with epoxy.
TMS WAVEGUIDE FILTERS AT-A-GLANCE
The interface is normally in the appropriate waveguide size. However, for most types, integral coaxial transitions on one or both ports are available as options.
TMS combines excellent filter design characteristics with years of experience to offer its customers a unique capability that meets the most demanding requirements where outstanding performance is needed in both production and engineering.
