Analog Devices' RMS Detector Accurately Measures Large Crest Factor Signals in 3G and 4G Devices
- With industry’s smallest footprint, Analog Devices’ ADL5505 TruPwr RMS detector allows optimization of the
linear power amplifier’s performance to increase efficiency and battery life.
NORWOOD, Mass.--(BUSINESS WIRE)--
Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal-processing
applications and leading provider of RF integrated circuits, is introducing a
TruPwr® RF power detector for 3G and 4G mobile terminals. The
ADL5505 TruPwr RF power detector is a highly accurate, easy-to-use device for determining the RMS (root mean
square) power of complex waveforms. It can be used for power measurements of both simple and complex waveforms and
is 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 optimizing the performance of linear power amplifiers.
Furthermore, with industry-leading specifications and the smallest footprint at a mere .8 mm x .8 mm, the
ADL5505 power detector eliminates the need for look-up tables and correction factors for large and changing
crest factors, significantly increasing efficiency, battery life and signal quality while reducing bill of
ADL5505 Key Features and Benefits
Excellent temperature stability across a 30 dB range and near 0 dB measurement error across temperature over
the top portion of the dynamic range.
Effective in high-frequency receiver and transmitter signal chains from 450 MHz to 6000 MHz.
Requires only a single supply between 2.5 V and 3.3 V, the detector draws less than 1.8 mA.
RMS output is a linear-responding dc voltage with a conversion gain of 1.86 V/V RMS at 900 MHz.
On-chip modulation filter provides sufficient averaging for most waveforms.
Pricing, Availability and Complementary Products
The ADL5505 is available now in a 0.8 mm x 0.8 mm WLCSP package and is priced at $2.50 per unit in 1,000-unit
quantities. In addition to the RMS power detectors, ADI has a wide range of products used within mobile terminals,
audio amplifiers, HDMI interfaces, lens driver components,
power management, and audio switches.
