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 ...

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 ...

The author is owner-engineer of AM Detuning Service. Currently there are more than 4,500 AM broadcast stations on the air in the U.S. These stations still rely, to a limited degree at least, on a ...

Dual-band impedance transformers and matching networks are pivotal components in modern high-frequency systems, facilitating efficient power transfer between disparate circuit elements by converting ...

We are specifically and deliberately going to do without the Smith chart today and look at some transmission line properties from a very basic perspective. Consider a transmission line, a coaxial ...
