Helicon isolator with quarter-wave nonreciprocal transformer





helicon isolator, quarter-wave nonreciprocal transformer, plated helicon resonator


The problem of design of the helicon isolators for the bottom of HF band is discussed. The usage of the quarter-wave helicon resonator with single-side metallization is proposed. Simulation and experimental results are presented.
