Hi all,
It has been a constructive session for the last hour after browsing all the threads on this topic. It provided me a surface understanding of the availability of methods around.
I wish to design a 1.5GHz BPF. I have been constructing a 7th order BPF based on AADE filter design software. I used the values provided at 1.5GHz and begin soldering the LC on a FR4 board. After 2wks, im still unable to produce one that barely make it near 1.5GHz. From these, i concluded that the filter software does not take parasitics and board substrate into considerations.
Is it possible to produce a 1.5GHz BPF? The LC values im dealing with are in terms of pico and nano. Its very difficult for me to achieve the exact values as per simulated. Is there any better filter software that accounts for parasitics and board details?
Im keen in exploring a microstrip BPF design and i have just started looking around. I have a few terms which im unsure of "tapped line", "center stubbed resonator".
Thank you all!
