To deliver the next generation of satellite services, operators are increasingly exploiting the benefits of wideband digital payloads. Broadband ADCs/DACs now directly digitise/re-construct IF/RF ...

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 ...

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 ...

Impedance matching is easy if you know the basics. Download the eBook to find out how. The L-network is a real workhorse impedance-matching circuit (see “Back to Basics: Impedance Matching (Part 2)” ) ...

This month we take a more in depth look at the tee network. This impedance matching network, aptly named, has the appearance of a T. The vast majority of AM transmission facilities will have at least ...

Impedance matching is easy if you know the basics. Download the eBook to find out how. During impedance matching, a specific electronic load (R L) is made to match a generator output impedance (R g) ...
