A radar phase shifter is described, of the type which includes several phase shift devices whose phase shift angles can be added together, which produces a minimal VSWR and an accurately controllable total phase shift. A five bit phase shifter includes devices that phase shift by angles that are nominally 11.25 DEG , 22.5 DEG , 45 DEG , 90 DEG , and 180 DEG . The 45 DEG device is located between the 90 DEG and 180 DEG devices to minimize the VSWR. In addition to the preset phase shift devices, an analog phase shifter device is provided which compensates for the inaccuracy of the other devices.
