SRF1 & SRF3
SRF Series Passive Splitter/Combiner
The SRF1 and SRF3 are compact, high performance, multi-channel, passive splitter/combiner arrays, designed for expansion of RF routing systems and other applications requiring high-density, rackmount splitter packages. The wide pass bandwidth includes the extended L-band range. The SRF series may be used in any L-Band signal distribution system where multiple channels of passive 1x2 or 1x4 splitter/combiners are needed.
The module functions as a splitter or combiner depending on the RF connections. The SRF unit can be configured as a splitter by injecting an RF signal to the common port. The outputs will be a reduced amplitude replica of the input signal. Injecting RF signals into the combiner input ports (splitter outputs) results in the summation at the common port with reduced amplitude. The monitor port allows monitoring of the common port without interruption of the signal path.
