Analog Devices (News - Alert), Inc., a manufacturer of high-performance integrated circuits used in analog and digital signal processing applications, has launched a TruPwr RF power detector for 3G and 4G mobile devices.
The ADL5505 TruPwr RF power detector is a very accurate and easy to use device. It finds out the RMS (root mean square) power of complicated waveforms. This power detector can be utilized for power measurements of simple and complex waveforms. It is mainly helpful for measuring high crest factor (high peak-to-RMS ratio) signals like WiMAX, CDMA2000, WLAN, W-CDMA and LTE (News - Alert) waveforms.
The ADL5505 TruPwr RF power detector is also of use in optimizing the performance of linear power amplifiers. The .8 mm x .8 mm ADL5505 power detector also gets rid of the needs to search for tales and correction factors for huge and changing crest factors. It increases efficiency, battery life and signal quality dramatically while lessening bill of materials expense.
The ADL5505 TruPwr RF power detector has outstanding temperature stability throughout a 30 dB range and near 0 dB measurement error across temperature over the top portion of the dynamic range. It is effective in high-frequency receiver and transmitter signal chains from 450 MHz to 6000 MHz, it only needs a single supply between 2.5 V and 3.3 V, the detector draws less than 1.8 mA, and its RMS output is a linear-responding dc voltage with a conversion gain of 1.86 V/V RMS at 900 MHz. the ADL5505's on-chip modulation filter also provides sufficient averaging for most waveforms.
The ADL5505 TruPwr RF power detector in a 0.8 mm x 0.8 mm WLCSP package is now available at $2.50 per unit in 1,000 unit quantities. ADI also has a broad range of products used in mobile devices such as audio amplifiers, lens driver components, MEMs accelerometers, HDMI interfaces, audio switches and power management.
ADI was in news last month for introducing clocking ICs for communications infrastructure.Anuradha Shukla is a contributing editor for TMCnet. To read more of Anuradha's article, please visit her columnist page.
