QWS Quarter-Wavelength Stub

Quarter Wavelength Stub Arrestor & Protector Circuit Diagram

Quarter Wavelength Shorted Stub arrestors provide excellent response and transient handling characteristics, do not age or wear out over time, and are DC-blocked by design.  Because they use an internal dead short, there is no “turn-on” or “response” time…Quarter wavelength stubs are “always-on” and limiting energy that is outside of the rated RF Pass Band(s).  QWS Models use a traditional T-style form factor in their designs for maximum retrofit/replacement capabilities.   Some of the QWS designs exhibit extremely wideband characteristics.
