I have been tinkering around with RF circuits lately.
Q1) Is it possible to design RF circuits like filters and power dividers in DesignSpark PCB?
Q2) If I'm designing a wideband RF power amplifier, as we know the RF feed lines could be a microstrip line or a CPWG, but the width of the line is fixed for a certain frequency. How can I make this transmission line wideband?
For example, My PA chip has a bandwidth of 1GHz around the center freq of 2.4GHz, but the feed line(transmission line) can be designed for a particular frequency only with a narrow band.
How are wideband PAs or other wideband devices fed using transmission lines?
