Power Detector offers optimal frequency performance, flexibility.

Press Release Summary:

Supplied in 4 x 4 mm, 16-lead LFCSP, ADL5906 TruPwr™ RMS Power Detector requires single supply of 5 V and few capacitors and can be driven with single-ended or differential input drive. Detector supports RMS-to-DC conversion from 10 MHz to 10 GHz and offers single-ended ±1 dB detection range of up to 67 dB at 2,140 MHz without requiring balun or external input matching. Response-independent of waveform types, product operates from -55 to +125°C and offers power-down capability to 250 µA.

Original Press Release:

Analog Devices' RMS Power Detector Offers Unparalleled Frequency Performance and Flexibility

NORWOOD, Mass.--Analog Devices, Inc. (ADI), a world leader in high-performance semiconductors for signal processing applications and RF ICs, today introduced a high performance RMS power detector. Featuring operation up to 10 GHz and a 67 dB measurement range, the ADL5906 TruPwr™ RMS detector is frequency versatile and eliminates the need for external input tuning devices, such as a balun. The ADL5906 RF detector is well-suited for a variety of applications that require an accurate RMS measurement of signal power including communications infrastructure, power amplifier linearization, Point-to-Point and Point-to-MultiPoint, cable, military, satellite, instrumentation equipment and ISM band transmitters.

Requiring only a single supply of 5V and a few capacitors, the new ADL5906 power detector is easy-to-use and capable of being driven with a single-ended or differential input drive. Furthermore, the ADL5906 provides low temperature drift across a broad -55ºC to +125ºC that is highly repeatable from part-to-part, thereby reducing design risk and manufacturing costs.

ADL5906 TruPwr RMS Power Detector Key Features:

• Accurate RMS-to-dc conversion from 10 MHz to 10 GHz

• Single-ended ± 1dB detection range: 67 dB at 2140 MHz, no balun or external input matching required

• Response-independent of waveform types such as GSM/CDMA/W-CDMA/TD-SCDMA/WiMAX/LTE

• Linear-in-decibels output, scaled 55 mV/dB at 2140 MHz

• Temperature stability of < ±1 dB from -40°C to +85°C

• Operates from -55°C to +125°C

• Power-down capability to 250 µA

• Pin-compatible with the ADL5902 and AD8363 TruPwr™ detectors
