【摘要】：LTCC(Low Temperature Co-fired Ceramic)技術(shù)是于1982年由休斯公司開發(fā)的新型材料技術(shù)。該技術(shù)能將無源元件集成在基片內(nèi)部,并且在其表面可貼裝IC和有源芯片,制成無源和有源的集成功能模塊。均衡器主要用于和放大器一起構(gòu)成固態(tài)驅(qū)動(dòng)放大模塊去驅(qū)動(dòng)行波管放大器,保證行波管的輸出曲線比較平坦。較高的均衡精度、足夠大的均衡量、較小的插入損耗和回波損耗是設(shè)計(jì)均衡器時(shí)需要著重考慮的指標(biāo)。LTCC的多層布線能力有利于均衡器的小型化設(shè)計(jì)。延遲組件作為相控陣?yán)走_(dá)的重要部件之一,其進(jìn)一步的發(fā)展將有助于提高整個(gè)相控陣?yán)走_(dá)的性能。用于將電信號(hào)延遲一段時(shí)間的器件叫做延遲線,當(dāng)將延遲線與開關(guān)結(jié)合在一起能夠?qū)崿F(xiàn)具體的延遲功能的器件就叫延遲組件。延遲組件要求具有較小的色散和插入損耗、較高的相位精度和比較平坦的幅頻特性。本文在針對(duì)均衡器的理論做了詳細(xì)分析之后,根據(jù)LTCC技術(shù)的工藝特點(diǎn),設(shè)計(jì)出了一種新型的基于LTCC技術(shù)的三維的復(fù)合左右手傳輸線諧振枝節(jié),詳細(xì)的分析了該諧振枝節(jié)對(duì)諧振頻率、均衡量和帶寬等指標(biāo)的控制。采用該諧振枝節(jié)設(shè)計(jì)制作的均衡器的尺寸得到了很大的縮小,對(duì)均衡器的小型化研究具有重要意義,并且由于可調(diào)參數(shù)較多,使得均衡器的可調(diào)性大大增強(qiáng)。最后設(shè)計(jì)制作了兩個(gè)頻帶的均衡器,分別工作在2~6GHz和6~18GHz,測試結(jié)果與仿真結(jié)果基本一致。接著對(duì)LTCC延遲組件的無源結(jié)構(gòu)進(jìn)行了研究,分析了切角對(duì)相位的影響,研究了平行雙線之間的耦合,最后對(duì)LTCC中的隔離孔做了分析研究,針對(duì)延遲組件設(shè)計(jì)了相應(yīng)的直流控制電路。在上述工作的基礎(chǔ)上,仿真設(shè)計(jì)了基于LTCC技術(shù)的延遲段和直通段。最后結(jié)合開關(guān)芯片設(shè)計(jì)了一款工作在Ka波段的6位延遲組件,該延遲組件具體尺寸為68mm×48mm×15mm,測試結(jié)果為:插入損耗小于等于35.3dB,駐波小于等于1.93,帶內(nèi)波動(dòng)小于等于2.6dB,相位線性度小于等于17?,滿足指標(biāo)要求。
[Abstract]:LTCC (Low Temperature Co-fired Ceramic) is a new material technology developed by Hughes in 1982. The technology can integrate passive components into the substrate and mount IC and active chip on its surface to make passive and active integrated function modules. The equalizer is mainly used to drive the TWT amplifier with the solid-state driving amplifier to ensure that the TWT output curve is relatively flat. Higher equalization accuracy, large enough equalization quantity, small insertion loss and echo loss are important indexes to be considered in the design of equalizer. The multilayer cabling ability of LTCC is beneficial to the miniaturization design of equalizer. As one of the important components of phased array radar, the further development of delay module will help to improve the performance of the whole phased array radar. A device used to delay an electrical signal for a period of time is called a delay line. When a delay line is combined with a switch to achieve a specific delay function, it is called a delay component. Delay components require smaller dispersion and insertion loss, higher phase accuracy and flat amplitude-frequency characteristics. After the detailed analysis of the theory of equalizer and according to the technological characteristics of LTCC technology, a new three-dimension resonant branch of compound left-hand transmission line based on LTCC technology is designed in this paper. The control of resonance frequency, equalization and bandwidth is analyzed in detail. The size of the equalizer designed with the resonant branch is greatly reduced, which is of great significance to the study of the miniaturization of the equalizer, and the tunability of the equalizer is greatly enhanced because of the large number of adjustable parameters. Finally, two band equalizers are designed and fabricated, which work in 2~6GHz and 61GHz, respectively. The test results are in good agreement with the simulation results. Then, the passive structure of LTCC delay module is studied, the influence of tangent angle on phase is analyzed, and the coupling between parallel two lines is studied. Finally, the isolation hole in LTCC is analyzed and studied. The DC control circuit is designed for the delay module. Based on the above work, the delay section and through section based on LTCC technology are simulated and designed. Finally, a 6-bit delay module working in Ka band is designed based on switch chip. The specific size of the delay module is 68mm 脳 48mm 脳 15mm. The test results show that the insertion loss is less than or equal to 35.3dB, the standing wave is less than or equal to 1.93, the in-band fluctuation is less than or equal to 2.6dB, and the phase linearity is less than or equal to 17db.
