Attenuation parameters, passband frequencies, and edge frequencies can be set to adjust the filter response. A Chebychev filter is chosen as the filter type in this example. The filter smart component is used to design the filter. The parameters can be easily adjusted to create custom designs. The filter design guide is a great starting point for designing filters. ADS (Advanced Design System) comes with a filter design guide to assist in creating filters to meet specific specifications. In conclusion, designing and simulating filters can be a complex process, but with the right tools and calculations, it is possible to create effective and efficient filters for various applications.įilter Design Made Simpler with Filter DesignGuide We used Keysight ADS to simulate and display the filter designs, and optimized the band pass filter for better performance. We designed the band pass filter by subtracting the cutoff frequencies of the low pass and high pass filters to arrive at the bandwidth, and then calculating the element values using a Chevychev design. We calculated the inductor and capacitor values based on the number of elements in the filter. For the high pass filter, we used a 0.1 dB ripple and a cutoff frequency of 24.5 GHz. For the low pass filter, we used a 0.2 dB ripple and a cutoff frequency of 27.5 GHz. We used five elements for the low pass and high pass filter designs, and three elements for the band pass filter design.

Today, we discussed how to design and simulate filters, specifically low pass, high pass, and band pass filters using Keysight ADS simulation software. How to Design and Simulate Filters LPF, HPF and BPF using Keysight ADS By analyzing the results, we can see that our circuit has a critical frequency of 2 gigahertz, insertion loss of less than 1 dB at frequencies up to 1.6 gigahertz, and a return loss of less than minus 30 dB in the S-band, which is quite good.

With the help of the S-parameter simulations and the ADS tuning tool, we can easily tune our design and make improvements.
