Suspended Substrate Filters

Realizing complex transfer functions requiring multiple filter topologies in a single package is an option few filter companies can offer. Our engineers are experts in multiple topology suspended substrate designs. Combining both lumped and distributed elements onto one suspended substrate board, provides enhanced unloaded Q and exceptionally low insertion loss smaller package sizes, than using any single topology alone.

Suited for Integrated Topologies

Our engineers select Cauer, pole-placed transfer functions in many of their suspended substrate designs, resulting in highly selective, low insertion loss devices. In addition, the compact structure and the flexibility of the printed circuit technology make suspended substrate designs particularly well suited for integrated topologies. 		suspended substrate filter

Ideally Suited to Volume Production

The wide range of realizable impedance values makes this medium particularly suitable for highpass and lowpass filters that can be cascaded together to form broadband Bandpass Filters and Multiplexers. It can also be used for printed combline and halfwave parallel coupled filters in narrowband applications. In this case proprietary temperature compensation techniques are used to ensure frequency stability. Suspended Substrate Stripline devices offer low parts count, small volume, light weight and are ideally suited to volume production.

Superior Temperature Stabilities

Sage Labs uses unique, proprietary techniques for temperature compensation and can offer temperature stabilities of ±0.1% over -55°C to +125°C. 		suspended substrate filter
