Ferroelectric-tunable microwave branching couplers |
| 摘要 |
The invention discloses the utilization of various transmission lines that entail a ferroelectric material as dielectric substrate to introduce an impedance shift by means of an externally applied d.c. bias, which alters the effective length between the input and output signals of the transmission lines of microwave couplers.
