| Sumario: | Microwave systems are used to generate, process and detect electromagnetic signals in a frequency range from 300MHz to 300GHz approximately. Applications of these systems are very varied: the radar (for locating people, time prediction and air and ground traffic control), broadcast (cellular, T.V, internet, data) through terrestrial (repeaters) and spacial links (satellite communications), wireless communication systems, et cetera. All these applications need a fundamental component: the microwave filter. Its function is to allow the pass of a defined range of frequencies with a minimum loss of power and with a low level of distortion. Currently, the design of filters capable of suppressing interference cause by external sources is a subject of vital importance in the microwave field. In this work, we present the design, simulation and characterization of two balanced band-pass filters in the microwave range. These filters present a fractional bandwidth of about 5.5% with insertion loss between 2.7 and 4dB in the bandpass. The maximum common mode rejection is about 67dB in the bandpass. The filters present a compact size compared to similar previous works. The filters are based on a novel balanced resonant structure composed of inductors, capacitors and transmission lines, which can resonate under differential mode and suppress common mode noise. |
