Teledyne Defence & Space's (TDS) patented designs have produced a number of different types of filters incorporating switches. These are all generally wideband for Electronic Warfare applications and enable the control of the frequency spectrum into any given system.

 Units are configured with a single or multiple inputs to single or multiple filtered outputs. As an example the SA002 features 8 Channels switchable over the frequency range 2-18GHz while the SA004 offers 17 channels over the 0.5-18GHz bandwidth.

In addition to these features each of the bands within the unit can overlap if this is desired. This enables the input frequency characteristic to be controlled even if the bands are not adjacent.
