Phase Shifter for Microwave Bridge Circuit is used to change the effective electrical length of transmission line without changing its physical length. The Phase Shifter is mainly used in microwave bridge circuit where phase and amplitude must be adjusted independently. The Phase Shifter is controlled by a micrometer driven mechanism which ensures optimum resolution in each waveguide. Phase Shifter for Microwave Bridge Circuit can be availed with a calibration chart of centre frequency of each band to cater to specific requirement.
