What is the minimun power to detect out of the Linear Dynamic Range?

Fo example, at  5.8GHz, the minimun in the  linear region is about -37dBm. Can detect -50dBm out of Liner region?

  • Hi Robert,

    Compensation doesn't seem possible, because for low levels like -45 to -50 dBm, output voltage is hitting the ground rail:

    A better solution would be to use an RF amplifier in front of the detector, or use a more sensitive detector, for example ADL5902 or LTC5582. The best choice depends on frequency range and dynamic range requirements.
