At Ferrite cored RF chokes in Class-E RF power amplifiers a design was offered for a choke using a Fair-rite 2843000202 core (commonly sold as a BN43-202), and the point was made that some products sold as BN43-202 might be significantly different.
Let’s look at the calibrated model estimates of choke impedance and core loss, side by side. Continue reading Ferrite cored RF chokes in Class-E RF power amplifiers – core material issues
