Abstract (en)
An RF reflection type phase shifter (RTPS) comprising a coupling device coupled to multiple reflective loads, n, respective ones of which include at least one variable reactance device with maximum reactance, X max , and, minimum reactance, X min , and at least two impedance transformers the characteristic impedances of which are selected according to predefined criteria to provide an increase in the value of a phase shift to be applied to a signal input to the RTPS proportional to the value of n.
