【摘要】：隨著無線通信的發(fā)展,人們希望終端設(shè)備能夠小型化而且能盡量兼容多個通信協(xié)議,同時電能消耗要盡量小,這就要求電路的尺寸也要盡量小。因此選擇性好、體積小及易于加工成了濾波器這一通信系統(tǒng)中的重要組成部分的基本要求。同時多頻濾波器和電調(diào)濾波器也因其能減小電路體積而獲得了大量的關(guān)注。設(shè)計(jì)多功能電路也是一個可以減小電路尺寸和損耗的方法,近來這類設(shè)計(jì)也逐漸興起。本文主要是基于小型化帶通濾波器及多功能濾波電路設(shè)計(jì),具體研究內(nèi)容分為以下三個部分:1、基于單枝節(jié)加載的單頻、多頻、電調(diào)濾波器,包括基于枝節(jié)線中心加載的兩端開路諧振器,并利用選擇性耦合所設(shè)計(jì)的毫米波濾波器;基于短路單枝節(jié)線中心加載的兩端開路諧振器所設(shè)計(jì)的三通帶濾波器;基于變?nèi)荻䴓O管中心加載的兩端短路的諧振器所設(shè)計(jì)的低通帶可調(diào)而高通帶固定的電調(diào)濾波器。文章首先分析諧振器的諧振模式,然后使用仿真軟件進(jìn)行全波仿真。仿真和測試結(jié)果的一致性驗(yàn)證了所提出的方法的可行性。其內(nèi)容成果已經(jīng)在期刊Micorwave and Optical Technology Letters和國際會議IEEE International Wireless Syposium上發(fā)表。2、基于多枝節(jié)加載的多頻帶通濾波器。根據(jù)奇偶模的原理,提出了多個新型的多模諧振器。同時經(jīng)過理論分析發(fā)現(xiàn)這些模式都可以方便地控制,因此可以用來設(shè)計(jì)多通帶濾波器。這些電路包括一個四模諧振器,其被用來設(shè)計(jì)頻率和帶寬都可控的雙通帶濾波器;一個六模諧振器,其被用來設(shè)計(jì)頻率和帶寬都可控的三通帶濾波器;一個八模諧振器,其被用來設(shè)計(jì)可以覆蓋5G Wi Fi頻段的三通帶濾波器。這些研究果已經(jīng)在IEEE Transactions on Microwave Theory and Techniques,IEEE Microwave and Wireless Component Letters上發(fā)表。3、帶有濾波效果的功分器和功放。其中濾波功分器包括一個基于集總元件的濾波功分器,一個電調(diào)濾波功分器和一個雙頻的濾波功分器,其中前面兩個是首次提出。濾波功放電路是將濾波器當(dāng)做阻抗變換器植入到功放的輸出匹配電路中,使得功放在保持高效率的同時帶有濾波響應(yīng)。這些研究成果已經(jīng)在IEEE Microwave and Wireless Component Letters等期刊上發(fā)表。

[Abstract]:With the development of wireless communication, it is desired that the terminal device can be miniaturized and compatible with a plurality of communication protocols as much as possible, while the power consumption is to be as small as possible, which requires that the size of the circuit be as small as possible. Thus the selectivity is good, the volume is small, and the basic requirements of the important components in the communication system of the filter are easily processed. At the same time, the multi-frequency filter and the electric-modulation filter are also subject to a large amount of attention due to the fact that the circuit volume can be reduced. The design of a multi-function circuit is also a way to reduce the size and loss of the circuit, which has recently emerged. This paper is based on the small-size band-pass filter and the multi-function filter circuit design, and the specific research contents are divided into the following three parts:1. Single-frequency, multi-frequency and electric-tone filter based on single-branch section loading, including two-end open-circuit resonators loaded on the center of the branch line, and a three-way band filter designed by the two-end open-circuit resonator loaded at the center of the short-circuit single-branch section line is utilized; A low pass band adjustable and high-pass band-fixed electrical tuning filter designed based on a resonator with two-end short-circuit loaded at the center of the varactor diode. First, the resonant mode of the resonator is analyzed, and the simulation software is used for full-wave simulation. The consistency of the simulation and test results verifies the feasibility of the proposed method. The results of the content have been published in the journal Micorwave and Optical Technology Letters and International Conference, IEEE International Wireless Symposium.2. Multi-band pass filters based on multi-branch-section loading. According to the principle of the parity mode, a plurality of novel multi-mode resonators are proposed. At the same time, it is found that these modes can be easily controlled through the theoretical analysis, so it can be used to design the multi-pass band filter. these circuits include a four-mode resonator that is used to design a dual-pass band filter that is both frequency and bandwidth controllable; a six-mode resonator that is used to design a three-way band filter that is both frequency and bandwidth controllable; an eight-mode resonator, It is used to design a three-way band filter that can cover the 5G Wi-Fi frequency band. These studies have been published in IEEE Transactions on Microwave Theory and Techniques, IEEE Microwave and Wireless Component Letters.3. Power divider with filtering effect and power amplifier. The filter power divider comprises a filter power divider based on a lumped element, an electric tone filter power divider and a double-frequency filter power divider, wherein the front two are first proposed. The filter power amplifier circuit is used as an impedance converter to be implanted into the output matching circuit of the power amplifier, so that the work is kept high and the filtering response is carried out at the same time. The results have been published in the IEEE Microwave and Wireless Component Letters.
