Abstract :
In this paper, a 3-bit digital pin diode phase shifter of the hybrid-coupled reflection type is designed and fabricated for mobile DBS application of an active phased array antenna system. Its fractional bandwidth is about 17% (VSWR=2:1). The theoretical considerations for the phase shifter design are briefly described. The experimental results for the fabricated 3-bit phase shifter such as the insertion loss and phase response, and its variations according to each phase state are presented, and also the overall insertion loss variations due to the forward current variations of each pin diode used in the phase shifter are given and a discussion of these results made in the system application aspect
