RMS power detector claims unparalleled frequency performance and flexibility
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 linearisation, Point-to-Point and Point-to-MultiPoint, cable, military, satellite, instrumentation equipment and ISM band transmitters.
Requiring a single supply of 5 V 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 features accurate RMS-to-dc conversion from 10 MHz to 10 GHz. The device has a 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.
The device, which has a power-down capability to 250 µA, also has a temperature stability of < ±1 dB from -40°C to +85°C and operates from -55°C to +125°C.
Availability and Pricing
The ADL5906 TruPwr RMS detector packaged in 4 mm x 4 mm 16-lead LFCSP is now available and priced at $5.59 each In 1,000 quantities.
