FIELD: electricity. ^ SUBSTANCE: invention refers to electrical engineering and can be used in output matching devices of radio transmitters (radio receivers) with impedance loadings (antennas), in beam synthesiser of antenna arrays, variable delay lines, etc. The discrete reactive circuit (DRC) comprises the first of N and the second of M group of discrete reactive element (DRE) connected to the outputs of the DRC by controlled switches (CS). Rated DREs in the first and second groups are chosen such that ai=aminki, where amjn is a minimal discrete variation increment of total rated aggregate DREs, ki=F(i) is a weight factor of i-th DRE calculated by function F(i) of recurrence series. According to the first version, DREs of the first and second groups are calculated by the identical functions F(i): of Fibonacci or Lucke series. Under the third version - by differing functions F(i). According to the second and the fourth versions, the DRC comprises the auxiliary DRE introduced. ^ EFFECT: higher reservation divisibility of rated discrete output value of a discrete reactive circuit (DRC). ^ 10 cl, 4 dwg, 7 tbl |
