BEAM STEERING CONTROLLER FOR CONTROLLING PHASE SHIFTER WITH MEMS SWITCH IN PHASED ARRAY ANTENNA

摘要

PURPOSE: A beam steering controller for controlling phase shifter with MEMS switch in a phased array antenna is provided to implement miniaturization and light with minimum costs by controlling the MEMS switch to be turned on/off through a LS2HP converter with only driving current. CONSTITUTION: In a beam steering controller for controlling phase shifter with MEMS switch in a phased array antenna, the beam steering controller calculates phase data corresponding to a phase shifter according to a beam steering command signal. The beam steering controller transmits more than one of phase data to phase array antenna drivers(110,120) which control the MEMS switch of the phase shifter corresponding to the phase data form the beam steering controller. The phase array antenna drivers includes a phase shifter and an LS2HP(Low-voltage Serial to High-voltage Parallel) converter.
