NI AWR Design Environment Application Note Now Available:
      “How to Improve Second-Harmonic Passband Rejection Microstrip Side-Coupled Filters”

EL SEGUNDO, California – March 2, 2015


NI/AWR "How to Improve Second-Harmonic Passband Rejection Microstrip Side-Coupled Filters" - RF CafeWhat:

NI (formerly AWR Corporation) released a new NI AWR Design Environment application note, “Improving the Second-harmonic Pass Band Rejection of Microstrip Side-coupled Filters.” Because of their low cost and easy manufacturability, side-coupled filters constructed from printed-circuit board (PCB)-based microstrip are widely used throughout the industry. One of the main drawbacks of the side-coupled filter is its limited rejection of the second harmonic. This application note demonstrates a solution that mitigates this problem through the introduction of notch-filter elements that improve the overall rejection of side-coupled filters at the second harmonic without significantly affecting the filter passband behavior.



The application note (English, Japanese and Chinese versions available) can be viewed and downloaded at http://www.awrcorp.com/solutions/technical-papers.
