The Design of a Low Loss Light-Weight S-Band Phase Shifter,

Abstract

This paper discusses the design and fabrication of a low loss, light-weight 4 bit phase shifter for use in airborne phased array antenna applications. The phase shifter operates over the 2.2 to 2.3 GHz frequency band with a maximum average insertion loss of 1.0 dB over the 16 possible states. It dissipates less than 30 mW power. The entire assembly consists of four levels of circuitry packaged into a right circular cylinder weighing 1.2 ounces and measuring 2.80 inches (outer diameter) and .75 inches thick. Novel packaging techniques resulted in the use of a one layer, thin (.002 inch), flexible circuit, folded between ground planes and low loss dielectric spacers. The use of one flexible circuit allowed all circuit metallization and RF interconnecting to be done simultaneously during the printing and etching fabrication process. (Author)
