Any grizzled electronic engineer will tell you that RF work is hard. Maintaining impedance matching may be a case of cutting wires to length at lower frequencies, but into the low centimetre and ...

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 ...

Two new ICs are described as fully integrated devices that offer direct capacitance-to-digital and impedance-to-digital conversion. The single-chip AD7745 integrates all stages of ...

When creating designs, engineers must meet or exceed their objectives for instrumentation and measurement equipment. Having accurate and correct instruments for test and measurement methods and ...

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 ...

In RF circuits, it's often necessary to match one impedance to another. The program in the Listing 1 can design a network to match any resistive impedance R 1 to another R 2 (where R 1 is less than R ...
