Impedance mismatches in a radio-frequency (RF) electrical transmission line cause power loss and reflected energy. Voltage standing wave ratio (VSWR) is a way to measure transmission line ...

Even a newly installed transmission line is not perfect. You bolt together the new sections properly, install all bullets and tighten all the bolts, but still ...

Peregrine Semiconductor’s DuNE technology solves one of the orneriest problems in RF design—antenna impedance matching. In every wireless application, an antenna has to be connected to the radio. That ...

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 ...

The purpose of this article is to explain, in detail, the process involved in building and tuning a high-frequency (HF) RFID antenna, which would operate at 13.56 MHz. Some concepts will be explained ...

You have probably heard the statement about standing wave ratio: “I changed the length of the transmission line and reduced the SWR.” Or the opposite statement, “I changed the length of the ...

Abstract: Impedance mismatches in a radio-frequency (RF) electrical transmission line cause power loss and reflected energy. Voltage standing wave ratio (VSWR) is a way to measure transmission line ...
