Microlab ST series trombone line stretchers are designed to adjust the electrical separation of other components without introducing additional mismatch or loss. They consist of two single SR Series stretchers, mounted in series, providing twice the phase range for a given physical size. All step discontinuities have been carefully compensated.
The Microlab/FXR line stretchers are constant impedance devices utilizing a unique inner design eliminating the step discontinuities associated with conventional line stretchers. They are rugged, well designed devices with a proven history.
Options for different polarity or alternate connectors are available upon request
