RFS21502BAA000 Rev C
Model — RFS 2150/2
Part No. RFS21502BAA000
L-Band RF Sensing Switch
General Description:
The
RFS21502BAA000
L-Band RF Sensing Switch provides two (2x1) L-Band sensing switches which detects
the presence of RF (primary) and provides the ability to switch to backup (secondary) on loss of primary. Each
of the sensing switches utilizes a DPDT high frequency relay that has the off path terminated into 75
Ω
. The
primary RF input is filtered, amplified, and detected to operate the relay. When the input level is above the
preset threshold, which is adjustable using the front panel up/down pushbuttons, the relay is energized and the
primary signal path is selected. When the signal falls below the preset threshold, the relay is de-energized and
the secondary signal path is selected. A front panel slide switch has been included to allow manual override to
the secondary input. The rear panel has been equipped with relay contact alarm outputs and a remote override
via contact closure.
