AD8313:  0.1 GHz TO 2.5 GHz, 70 dB Logarithmic Detector / Controller

Product Details


The AD8313 is an RF logarithmic detector and controller, with response extending from 0.1 to 2.5 GHz. The device is capable of accurately converting a modulated RF signal at its differential input to an equivalent decibel-scaled value at its dc output. The dynamic range is up to 70 dB with ±3 dB accuracy, or 62 dB to ±1 dB. The AD8313 is useful for RF transmitter and receiver power measurement and control applications. It is offered in a small eight-pin micro-SO package. Its application requires only the provision of a 2.7 V to 5.5 V power supply, along with input coupling and power supply decoupling capacitors.

An evaluation board is available for this product and may be ordered using the following product number: AD8313-EVAL. Schematic and layout for this evaluation board is contained in the product datasheet.

FEATURES and BENEFITS

  • Operating frequency: 0.1 GHz to 3.5 GHz
  • High dynamic range: 70 dB to ±3.0 dB
  • High accuracy: ±1.0 dB over 65 dB range (@ 1.9 GHz)
  • Fast response: 40 ns full-scale typical
  • Controller mode with error output
  • Scaling stable over supply and temperature
  • Wide supply range: 2.7 V to 5.5 V
  • Low power: 13.7 mA at 5 V
  • Power-down feature: 20 µA at 3 V
