Abstract
A new coupled-line directional coupler, convenient for PCB and LTCC applications, is proposed. The coupler covers -10 dB to -2.7 dB coupling coefficient, being always theoretically compensated. The novel structure is not sensitive to lateral misalignment of conductive layers, and not sensitive to thickness and dielectric permittivity tolerances of applied dielectric substrates. Promising experimental results are presented.
