Product Description

QuinStar Technology offers QJB and QJD series Precision Bi-directional and Dual-directional High Directivity Couplers, which cover a frequency range of 18 to 220 GHz in twelve waveguide bands. Coupling values of 10, 20, 30 and 40 dB are available. In a dual directional coupler, the forward and reverse coupling values can be made different. The units are designed with a rugged split-block mechanical structure for long-lasting durability to maintain the precision coupling values. The bi- and dual-directional precision high directivity couplers are ideal devices in the applications of simultaneously testing, sampling or monitoring signals in both directions of the main arm of the coupler. Examples include instrumentation for incident and return signal measurement such as radar transmitted/reflected signal monitoring, etc.
