The LTC5596 is a high accuracy RMS power detector that provides a very wide RF input bandwidth, from 100MHz up to 40GHz. This makes the device suitable for a wide range of RF and microwave applications, such as point-to-point microwave links, instrumentation and power control applications.

The DC output voltage of the detector is an accurate representation of the average signal power applied to the RF input. The response is linear-in-dB with 29mV/dB logarithmic slope over a 35dB dynamic range with typically better than ±1dB accuracy. The detector is particularly suited for measurement of waveforms with crest factor (CF) as high as 12dB, and waveforms that exhibit a significant variation of the crest factor during the measurement.

To achieve higher accuracy and lower output ripple, the averaging bandwidth can be externally adjusted by a capacitor connected between the FLTR and OUT pins.

The enable interface switches the device between active measurement mode and a low power shutdown mode.

Applications

  • Point-to-Point Microwave Links
  • Instrumentation and Measurement Equipment
  • Military Radios
  • LTE, WiFi, WiMax Wireless Networks
  • RMS Power Measurement
  • Receive and Transmit Gain Control
  • RF PA Transmit Power Control

LTC5596 Linduino Shield 100MHz to 40 GHz RMS Power Detector

Product Detail

Demonstration circuit DC2870A is a Linduino® shield for Mean-Squared Power Detector LTC5596. It is set up for quick evaluation of RMS RF power measurement using the Arduino/Linduino compatible platform and software download available here. When connected to PC with USB cable, accurate power level can be monitored using the graphic user interface.

The LTC5596 is a wide dynamic range linear-in-dB Mean Squared RF Power Detector, operational from 100MHz to 40GHz. The Linduino (DC2026C) platform provides 10-bit ADC at 4.9mV/LSB resolution with 5V default reference voltage. Input dynamic range with 1dB accuracy is up to 35dB depending on frequency. The detector output slope is normally 6 LSB/dB. The DC2870A Demo Circuit is optimized for wide operational frequency signals up to 40GHz using the 2.9mm SMK edge mount connector. Input impedance is internally matched to 50Ω. It is suitable for RMS measurements of high crest factor waveforms up to 12dB peak-to-average. No external coupling capacitor is necessary if DC voltage at RFIN pin is kept below 1.0V. On board 3.3V regulator provides power to the shield by jumper JP1.
