Quarter Wave Stub (QWS)
Specific Frequency Range
Citel’s PRC Series is a Quarter Wave Stub (QWS) surge arrestor designed for specific frequency bands. The PRC does not utilize any active components and allows only the specified frequency to pass thus eliminating low frequency transients. This design allows for very high surge handling capacity up to 100kA 8/20us. The PR is conveniently installed in series with the line and can be mounted via the standard grounding screw or bulkhead.
Available with the most commonly used connectors including BNC, F, N, SMA, TNC, and 7/16 Din connectors or it can be custom made for your application with any combination of connector and gender types to eliminate the need for any adapters.
In applications without a DC voltage on the line, a frequency band pass filter is clearly the best technology available because it has the highest surge handling capacity, lowest let-through voltage and requires no maintenance.
