Abstract

The phase-difference performance at two desired frequencies of the generalized dual-band unequal coupler is discussed and presented in this comment as supplementary information. The condition of {∠S21 - ∠S31 f1 + {∠S21 - ∠ {S31}f2} = π and the analytical equations for {∠S21 - ∠ {S31}f1 or f2 are provided. It can be concluded that the dual-frequency output phase differences are constant and equal to 90° when R2 = R3 but the values of R1} and R4} can be varied. Finally, the calculated results show that the phase-difference variations about ±11% in the whole useful bandwidths of these branch-line couplers are objective and acceptable in common practical applications when R2 and R3 are in the range of 30-100 Ω (R2R3).
