Simulating a 40m bandpass filter in LTSpice

January 20, 2011 | Amateur Radio, electronics | By: Mark VandeWettering

A few days ago, I created a small program to compute bandpass filters using the equations from Experimental Methods in RF Design. Basically, you can pick a given inductor value, and then it solves for all the necessary capacitors. What wasn’t immediately obvious from the equations and the values that are generated was how these […]
