Product Description

QuinStar Technology’s QJR series precision high directivity couplers cover the frequency range of 18 to 170 GHz in nine waveguide bands. They are available in 3 port configurations with coupling values of 3, 6, 10, 20, 30 and 40 dB. They are constructed with a rugged split block mechan¬ical design for long-lasting durability to maintain their cou¬pling value. Precision high directivity directional couplers are ideal devices for sampling or inserting RF energy in a waveguide transmission line without affecting the transmitting signal. They prove especially useful in applications such as RF power and signal reflection measurements in test systems. The superior directivity, insertion loss, coupling flatness and accuracy also make these directional couplers useful for a wide range of laboratory requirements and subsystem applications. In addition to the standard three-port directional couplers, QuinStar offers custom four-port directional couplers. See series QJB couplers.
