RMS power detector scales the peaks
Ideally suited for next-generation radio-frequency applications using complex signals with highly varying peak-to-average ratios.
Analog Devices has a new RMS power detector that precisely measures signals with highly varying crest factors up to 6GHz used in WiMAX/802.16, WCDMA, TD-SCDMA and LTE applications The AD8363 supports the communications industry's focus on increasing efficiency and improving ease-of-use to reduce the overall system size and cost

Analog Devices is sampling two new low-cost ADSP-219x models - the ADSP-2195 and ADSP-2196 - expanding the ADSP-21xx family of code compatible digital signal processors.
14bit A/D conversion at 105Msample/s
Analog Devices is claiming another industry breakthrough with the first 14bit ADC to run at 105Msample/s.
The AD8363 targets high performance RF applications including power amplifier (PA) linearisation/control loops, transmitter power control, transmitter signal strength indication (TSSI) and RF instrumentation.
Accurate control of PA output power significantly reduces cost and improves efficiency.
TruPwr ICs are ADI's award winning portfolio of patented RMS detectors.
ADI offers one of the most extensive RMS portfolios in the market.
The AD8363 is ideally suited for next-generation radio frequency (RF) applications using complex signals with highly varying peak-to-average ratios.
The signal is sent directly into the single-ended input eliminating the need for an external balun, unlike power detectors from previous generations.
The AD8363 achieves +0.5dB accuracy over the entire 50+1dB dynamic range.
The output is linear-in-decibels, and scaled to 50mV/dB, but other slopes can be arranged.
The AD8363 is fully specified and stable over the entire frequency range of 50Hz to 6GHz, operating temperature range of -40 to +125C and supply voltage range of 4.5 to 5.5V.
With these specifications the most stringent power measurement applications can be accurately realised.
The AD8363 is currently sampling and will be available in production quantities in April 2008.
The device is packaged in a compact 16-lead 4 x 4mm LFCSP (lead-frame chip-scale package) with a price of US $5.25 per unit in 1000-piece quantities.
