NORWOOD,
Mass.--Feb. 11, 2008--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
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.
