Analog Devices, Inc. today introduced the AD8363 TruPwrTM root-mean-square (RMS) power detector that precisely measures signals with highly varying crest factors up to 6 GHz 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. The AD8363 targets high performance RF applications including power amplifier (PA) linearization/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. TruPwrTM 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 +/- 0.5 dB accuracy over the entire 50 dB +/- 1 dB dynamic range. The output is linear-in-dB, and scaled to 50 mV/dB, but other slopes can be arranged. The AD8363 is fully specified and stable over the entire frequency range of 50 Hz to 6 GHz, operating temperature range of -40 degrees C to 125 degrees C and supply voltage range of 4.5 to 5.5 V. With these specifications the most stringent power measurement applications can be accurately realized. For more information, visit http://www.analog.com/pr/AD8363.

Availability and Pricing

The AD8363 is currently sampling and will be available in production quantities in April 2008. The device is packaged in a compact 16-lead 4x4 mm LFCSP (lead-frame chip-scale package) with a price of $5.25 per unit in 1000-piece quantities.
