摘要：

This paper describes the realization of compact 360 degree phase-shifter MMICs using: thin-film BST varactors in a series cascade of all-pass networks. Unlike conventional delays line structures, all-pass networks provide constant phase shift with small variation of insertion loss. In similar fashion, very broadband phase-shifters can be implemented by cascading all-pass networks with staggered center-frequencies. Using a thin-film BST technology for the varactors, extremely compact and low-cost phase-shifter structures have been developed. Selected results are shown in the 1-30GHz range.
