Abstract
A precision microwave delay line fabricated using stripline techniques, but having features of a coaxial transmission line. The delay line is assembled from three pieces: a center board, an upper housing, and a lower housing. The center board is a nonconductive substrate with a stripline conductor. The stripline conductor defines a transmission path. The housings are made of conductive material. A channel is formed on the inner surface of each of the housings. The channels are arranged such that when the center board is sandwiched between the housings, the transmission path is contained within a uniform cross-section cavity formed by the channels. The housings are electrically connected to each other through the center board with plated-through holes at locations along the sides of the transmission path.
