Make a truly linear RF-power detector


Posted on May 27, 2012

Modern high-performance transmitters require accurate monitoring of RF power, because most cellular standards depend on strict power- transmission levels to maintain an effective network. Regulation of transmitted-signal strength also lets you build lower cost systems. Figure 1 shows a waveform-independent circuit that provides a linear measurement of RF power. Sophisticated modulation schemes, such as CDMA (code-division multiple access) and TDMA (time-division multiple access) have obsoleted traditional approaches to RF power.
