PRECISION DUAL DIRECTIONAL COUPLERS
QJD SERIES
Specifications and Ordering
Our designs are built onsite and upon request. We tailor each order through our sales engineers to better serve your purchase.
Description
QuinStar’s QJD Precision Dual Directional Couplers cover a frequency range of 18 – 220 GHz in twelve waveguide bands. Coupling values of 10, 20, 30, and 40 dB are available. In the dual directional coupler, the forward and reverse coupling values can be made different. We designed this unit with a rugged split-block mechanical structure to maintain the precision coupling values over use.
Applications
These couplers are ideal for 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.
