Cavity Filters

For applications where low insertion loss and high performance are important.

Cavity structures can be used to realise bandpass or bandstop filters and multiplexers where they can be used exclusively or integrated with other structures as the application requires. BSC have considerable experience in mechanical applications and are often employed to design the outline package for custom integration within the application saving on size and cost, whilst meeting tough environmental requirements.

Cavity structures give high Q performance, whilst the mechanics employed make them suitable for Military and Commercial applications where narrow bandwidth and ruggedness are important parameters. Cross coupling is used to greatly improve selectivity, whilst maintaining low Insertion Loss.

Cavities can be supplied as individual filters or integrated into banks or sub-assemblies. For broader stopband performance cavity structures can be combined with Tubular, Lumped Element, Suspended Substrate or Combline filters.
