Designing Filters Efficiently Using Simulation Tools
Sep 1, 2005
By Anurag Bhargava Filters are an integral part of any RF/microwave system. Designing one efficiently
and accurately can be a challenge, even when sophisticated simulation tools are
available. Electromagnetic simulation, which is more or less an integral part of
any commercial RF/microwave simulation software, can help designers meet this
challenge. As an example, this article gives two bandpass filter (BPF) examples
that were simulated using circuit and electromagnetic (EM) simulators and
compares the simulated and measured results....
