Abstract :
A low-loss broadband 6-b phase shifter has been developed in a form suitable for airborne phased array radar applications. A glass-based microwave circuit integration (GMIC, glass microwave integrated circuit) is used, in which thin-film, process-oriented photolithographic technology is used to realize all of the passive components on a glass surface. Hybrid-coupled reflection circuitry covers the frequency range of 6-18 GHz with losses averaging from about 3 dB at 6 GHz to about 8 dB at 18 GHz over the 64 phase states covering a 360 degrees range.<>
