Suspended substrate filters

500MHz to 26GHz

Filtronic’s filter experts design suspended substrate stripline filters for both broadband and narrowband filters; typical frequency range 500MHz to 26GHz.

The wide range of realisable impedance values makes this medium particularly suitable for high pass and low pass filters that can be cascaded together to form broadband band pass filters and multiplexers.

Generalised Chebychev filter prototype designs result in highly selective band edges with low passband loss and high stop-band attenuation.

As suspended substrate is a printed technology it exhibits very repeatable performance, and devices can be made with very tight amplitude and phase tracking. For some higher power applications, rather than use a substrate, solid metal bars are suspended in air forming low PIM filter structures.

Features:

  • Suitable for high pass and low pass filters that can be cascaded together to form broadband band pass filters and multiplexers.
  • Utilising printed circuit technology
  • Repeatable performance across narrowband and broadband applications
