ADI's RMS Detector Accurately Measures Large Crest Factor Signals
Analog Devices Inc. (ADI), a leader in high performance semiconductors for signal-processing applications and a provider of RF integrated circuits, is introducing a TruPwr® RF power detector for 3G and 4G mobile terminals. The ADL5505 TruPwr RF power detector is a highly accurate, easy-to-use device for determining the RMS (root mean square) power of complex waveforms. It can be used for power measurements of both simple and complex waveforms and is particularly useful for measuring high crest factor (high peak-to-RMS ratio) signals, such as W-CDMA, CDMA2000, WiMAX, WLAN and LTE waveforms. It is also effective for optimizing the performance of linear power amplifiers. Furthermore, with industry-leading specifications and the smallest footprint at a mere 0.8 mm x 0.8 mm, the ADL5505 power detector eliminates the need for look-up tables and correction factors for large and changing crest factors, significantly increasing efficiency, battery life and signal quality while reducing bill of materials cost.
