RFS Sensing Redundancy switch

	The RFS 2150 provides up 2 (or4) 2x1 L band sensing switches for detecting the presence of RF (primary) and switching to backup on the loss of primary.It uses a DPDT RF relay with the off path terminated in 75ohm. The primary RF is filtered, amplified and detected to operate the relay.Whilst the input level is above the, preset, threshold the relay is energised and the primary signal is selected. If the signal falls below the threshold then the relay is de-energised and the secondary path is selected.Models are also available for 70MHz ±18MHz and for 52MHz
