|
摘要
介绍了一种星载S频段上变频器的原理,并给出了基于低温共烧陶瓷(Low Temperature Co-fired Ceramic,简称LTCC)一体化技术的设计方法,详细描述了关键部件的设计,给出了设计实例,证明了基于LTCC技术星载微波多芯片组件(Multichip module,简称MCM)的可实现性。实际测试结果为:本振输入电平0 d Bm时变频增益约40 d B;噪声系数小于9 d B;对混频产物、本振信号、二次谐波的抑制分别大于等于56.5 d Bc、55.8 d Bc、77 d Bc;输出1d B压缩点≥9.56 d Bm;组件尺寸约为5.2 cm×4 cm×1.2 cm。
The principle of an S-band up-converter carried by satellite is presented,and the combined design method based on LTCC technology is given. The design of key components is described in detail,and a design example is given. The realizability of the MCM based on LTCC technology carried by satellite is demonstrated. The conversion gain of the MCM is about 40 d B with the local oscillator input power 0 d Bm. The noise figure is better than 9 d B. The useless mixed signals' suppression,the LO power suppression and the 2nd harmonic suppression are better than 56. 5 d Bc,55. 8 d Bc and 77 d Bc respectively. The 1 d B gain compression( output) is greater than 9. 56 d Bm. This MCM size is about 5. 2 cm×4 cm×1. 2cm.
