Impedance matching is easy if you know the basics. Download the eBook to find out how. Impedance matching is one of those design processes that you use to make circuits and equipment work properly. It ...

Non-Foster circuit design offers a transformative approach to overcoming the intrinsic limitations of traditional passive matching networks. By utilising active elements to generate negative impedance ...

If you catch a grizzled old radio amateur propping up the bar in the small hours, you will probably receive the gravelly-voiced Wisdom of the Ancients on impedance matching, antenna tuners, and LC ...

In January 2012 I looked at the venerable T network for impedance matching in AM antenna systems. Now I’ll discuss the L and Pi networks, and look at their use in antenna systems. The L network is the ...

When it comes to actual antennas in the real world, much of our knowledge is empirical. We know very broadly theories that explain how a point charge radiates (Maxwell’s equations), the need for ...

Designing a matching circuit is fairly straightforward for a buffered input ADC because it offers almost constant impedance across all frequencies. As we have already seen, this is not the case with ...

Something that all radio amateurs encounter sooner or later is the subject of impedance matching. If you’d like to make sure all that power is transferred from your transmitter into the antenna and ...

Antennas are mandatory for a product to connect via radio frequency. Obvious examples are cell phones, satellite communications, and even our garage-door openers. But the Internet of Things is ...
