IEEE Microwave Magazine – February 2020
The February issue of the IEEE Microwave Magazine is out! This issue features passive component technologies and applications. With passive components we think of filters, baluns, power combining networks and antennas and this issue has a bit of all of these. Our first feature explores negative group delay in equalizers, phase shifters, antennas and feedforward amplifiers. Our second feature explores multi-mode resonators which adds a fascinating dimension to compact filters. And our third feature takes the increasingly popular world of balanced power dividers a step further with passive and active tuning. And just to round things out with passive components we have an Application Note on matching with a binomial multi-section transformer.
