QuinStar Technology’s series QWU E-H tuners are available in nine waveguide bands. They provide full waveguide band coverage and are ideally suited for precision measurements, experimental testing and developmental tuning.
The E-H Tuners consist of a hybrid tee section with micro¬meter drive tunable shorts in both the E-plane and H-plane arms. These tuners introduce discontinuities into the waveguide transmission line for simultaneous control of both phase and amplitude of the RF reflection coefficient. They can be used as matching devices to cancel reflections in transmission lines or to match detectors, terminations or similar components.
