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
 What:
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.
Where:
The application note (English, Japanese and Chinese versions available) can be viewed and downloaded at

When:
Immediately.
