RF characteristics dispersion of the L-band glass-epoxy 5-bit phase shifter module using SW-BANK chips and low cost L, C chips

摘要

RF characteristics dispersion and reliability of the low cost L-band 5-bit phase shifter module is described. This phase shifter module consists of GaAs SW-BANK chips and chip inductors/capacitors mounted on glass-epoxy substrate. The calculated and fabricated RF characteristics dispersion of the phase shifter module show that the tolerance of chip inductors/capacitors is enough small for phase shifter use. The results of two reliability tests are indicated that this module configuration is feasible for a phase shifter.
