PURPOSE: A ferrite phase shifter module is provided to be mainly used for a 3-D multi-functional radar and et cetera. CONSTITUTION: A control board(210) is connected to a main control beam steering unit through a main connection unit(218). The control board communicates with an MCU of a microwave controller through a communication chip(217). The MCU(215) of the control board drives pulse signals according to a command received from the main control beam steering unit through an FPGA(213) and controls each phase shifter(100-1-100-16) through on/off switching of driving switches(212-1-212-16). An oscillator(214) provides a clock required for operation of the FPGA. An EPROM(216) mounts firmware and data so that the MCU can perform a phase shifter control algorithm. [Reference numerals] (100-1) Phase shifter 1; (100-16) Phase shifter 16; (212-1,HH,212-16) Switch IC; (217) Communication chip; (219) Power chip; (AA,BB,CC) Horn direction; (DD) Phase shifter 2; (EE,FF,GG) Radiation direction; (II) Beam steering unit
