FIELD: electronics.
SUBSTANCE: invention relates to electronics and can be used in signal processing technology, measuring technology. For this, a delay line is proposed, made on a flexible polymer base, twisted into a spiral, while the central conductor of a rectangular or circular cross-section is enclosed between two layers of equal thickness of a flexible polymer dielectric, each of which is coated on the outside with a conductive layer, thus forming a strip transmission line, while polypropylene or microwave polyimide is used as a dielectric base.
EFFECT: reduced non-uniformity of the transmission confidential, the non-uniformity of the group delay time, the dispersion of the group delay time.
