Embodiment

[0033] Such as Figure 1 to Figure 2 As shown, this embodiment provides a reconfigurable balun filter based on half-wavelength resonators. The reconfigurable balun filter is composed of three impedance resonators with the same structure, wherein the impedance resonators are printed On a dielectric substrate with a thickness of 25mil and a relative permittivity of 10.2. In this embodiment, the varactor diodes are selected from SMV123 series. It should be noted that the serial numbers such as "first", "second", and "third" in this embodiment are only used to distinguish similar components, and should not be understood as specific limitations on the scope of protection. In addition, directional terms such as "bottom", "top", and "edge" described in this embodiment are described based on the drawings.

[0034] Specifically, the reconfigurable balun filter includes a first impedance resonator, a second impedance resonator, and a third impedance resonator that are all attached to ...

Description

technical field [0001] The invention relates to the field of wireless communication systems, in particular to a reconfigurable balun filter based on a half-wavelength resonator. Background technique [0002] The balun filter is an independent microwave passive device, which functionally realizes the effective combination of the filter and the balun in the radio frequency circuit, that is to say, it has both the frequency selection characteristics of the filter and the balun Lun's unbalanced input signal into a balanced signal function. At the same time, the balun filter has the advantages of low cost, high integration, and miniaturization, and is widely used in balanced mixers, balanced push-pull amplifiers, and antenna feed networks. Nowadays, with the rapid development of modern wireless communication systems, spectrum resources are becoming increasingly tight, and more and more environments require electronic devices used in them to be tunable and multi-functional, so as...
