南京爱立信熊猫通信公司使用AWR软件，使得LTCC尺寸减少了80%

2013-06-27 来源：微波射频网 我要评论(0) 字号：大 中 小

南京爱立信熊猫通信有限公司(NEPCC)，亚洲最大的移动通信基站和系统设备制造商，使用AWR软件设计了一种新颖的多节堆叠式耦合器。NEPCC 的项目组长Nick Zhou,使用AWR的Microwave Office®电路设计软件结合AXIEM®平面电磁仿真来开发一个创新的垂直堆叠的多段结构，得以提高产品性能和降低设备尺寸。

Nick Zhou表示：“应用AWR软件，我们能够对LTCC耦合器进行设计和优化，带宽提高40%，体积减少80%。AWR的仿真结果与实测结果符合的非常好，当地工程师们的支持非常优秀。”

Nanjing Ericsson Panda Communications Reduces LTCC Footprint By 80 Percent Thanks To AWR Software

Customer Background

Nanjing Ericsson Panda Communication Co., Ltd. is a joint venture company established by Nanjing Panda Electronics Company Ltd., Ericsson Sweden, Ericsson (China ) Co., Ltd., China Putian Information Industry Group Co., Ltd., and Yung Shing Enterprise, Hong Kong, to manufacture high-technology communications system products, including the design, production, sales, and installation of GSM/CDMA digital mobile communication systems and switches. Incorporated in 1992, the company has become the largest manufacturing base of mobile communication base stations and system equipment and is rapidly becoming the largest system supply center for Ericsson in the Asia-Pacific region.

The Design Challenge

The quadrature hybrid (or branch-line coupler), is a key component found within microwave circuits such as balanced amplifiers, balanced mixers, phase shifters, and beam-forming networks for array antennas. The conventional approach for a single section quadrature hybrid with 20dB return loss is limited to 10 percent bandwidth. While a broader bandwidth can be achieved using coupled lines, coupled line hybrids are difficult to implement on MMICs. Looking instead at branch line hybrids, the bandwidth can be increased greatly by using stepped multi-section impedance transformers and cascading the multi-sections, however, the increase to the size of the MMIC is a deterrent. Therefore, the challenge for the NEPCC design team was to develop a novel approach for a quadrature hybrid that would not only decrease the size of the MMIC but also improve the performance bandwidth.

The Solution

Nick Zhou, lead AWR user at NEPCC, used AWR’s Microwave Office® circuit design software combined with AXIEM® planar EM simulation to design a novel low temperature co-fired ceramic (LTCC) quadrature hybrid device using a stacked multi-section structure based on a Ferro-A6 substrate. A bandwidth of 40 percent larger than conventional devices and a size reduction of 80 percent were achieved using a vertical stacked structure instead of the traditional cascaded method. The main advantages of this novel approach are miniaturized size and low interference.

Due to the large number of parameters, the optimization and verification would have been very time-consuming if simulated using only traditional FEM-based simulators. Because Microwave Office and AXIEM are closely integrated within the AWR Design Environment™ and share the same schematic/layout, Nick was able to combine the circuit-based simulator and EM-based simulator, which significantly enhanced his optimization efficiency as well as accuracy. In addition, there was no need to manually re-draw the layout, which saved even more time. The final simulated results versus measurements agreed very well and the design team was extremely pleased with the success of this difficult challenge.

Nick found AWR software to be easy to install, fast to learn, and very user friendly. He also appreciated the fast, proficient, and dedicated support by AWR’s local application engineers.
