ADI unveils rf power detector for 3G and 4G terminals
Analog Devices has announced a TruPwr rf power detector for 3G and 4G mobile terminals.
According to ADI, the ADL5505 TruPwr rf power detector is a highly accurate, easy-to-use device for determining the root mean square (RMS) power of complex waveforms. It is designed to be used for power measurements of both simple and complex waveforms and is said to be 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 optimising the performance of linear power amplifiers.
The ADL5505 power detector has been designed to eliminate the need for look-up tables and correction factors for large and changing crest factors. This, says ADI, will significantly increase efficiency, battery life and signal quality while reducing bill of materials cost.
The device is available now in a 0.8 by 0.8mm WLCSP package.
