Background technology
Power divider is the part on a basis in microwave circuit, because it has the function of separation and composite signal, so all will use in a lot of aerial arrays and balancing circuitry.And bandwidth-limited circuit is another kind of indispensable part in wireless communication system, because it can isolate the frequency band that needs.These two kinds of elements exist in many microwave systems simultaneously.
In the past few decades, a large amount of researchs about power divider are arranged.The focus of research is to widen frequency band, reduces area, and double frequency response and harmonic wave suppress.Meanwhile, bandwidth-limited circuit is also important field of research in the passive circuit design.Single-pass band and comb filtering circuit are two different research directions.The focus of research is to reduce volume, improves the aspects such as frequency selectivity, the operating frequency of controlling flexibly a plurality of passbands and bandwidth, increase transmission zero.
In a lot of Radio Frequency Subsystems, power divider and filter circuit need to link together to realize to separate the function with filtered signal usually.Yet their characteristic own is all just paid attention in the research of all power dividers above-mentioned and filter circuit, and the possibility of considering both combinations is seldom arranged.Usually use discrete devices in traditional system and realize this two functions, but size can be very large like this.
