Lumped element filters


We understand filter topology and can work with the perfect technology for each challenge, while offering rapid prototyping and reduced development cycles.

Lumped element technology is commonly used in applications where small size is required, especially at lower frequencies where transmission line devices might be excessively large.

Both narrowband and broadband designs are available in high pass, low pass, band pass, band stop and multiplexer form. Various filter prototypes are used combining capacitive or inductive coupling to produce asymmetric or symmetric responses.

Filtronic pays particular attention to the selection of components and the design of the housing so that parasitic resonances and waveguide modes are suppressed to ensure broad, spurious free stopbands.
