HF/UHF Low-Loss Nanosecond Variable Delay Lines.

Abstract

Two delay line techniques are described: one for the HF band and the other for the UHF band. Both lines are similar in that they are broadband, low-loss, low-impedance, and nanosecond variable. The HF delay line is electrically variable and utilizes ceramic dielectric and ferrite materials in a coaxial line configuration. The UHF delay line is mechanically variable and utilizes coupled helical transmission lines. The design principles for the two delay lines are discussed and the construction details are described. Characteristics of both lines are measured and data presented in graphical form. (Author)
