NI AWR Design Environment Enables Nanjing University Students to Design Miniaturized Bandpass Filter

EL SEGUNDO, Calif.  June 3, 2015 -- NI (formerly AWR Corporation) announces that Nanjing University of Science and Technology (NUST) electronic engineering students have designed a miniaturized bandpass filter (BPF) using NI AWR Design Environment™ software. BPFs are essential in many modern system-in-package applications, but are also among the largest components, making it difficult to achieve the small footprint demanded for today’s communication products without sacrificing performance. NUST students set out to design a miniaturized lumped-element 10-layer low temperature co-fired ceramic (LTCC) BPF of which the main challenge was size reduction.

“There was no easy way before to construct the models for vertically multilayer interdigital capacitors and multilayer spiral inductors in the coordinate oriented software,” said NUST students Bo Zhou, Weixing Shent, and Yiyuan Zheng. “Microwave Office software offers a very easy and efficient way to design LTCCs using its built-in process definition tool. Also, we can easily tune, sweep, and optimize the value of the capacitors and inductors using the cutting-edge electromagnetic simulator of AXIEM.”
