  • Amplitude Detectors with Isolators

    ERAVANT

    Full band waveguide detectors are GaAs beam lead Schottky diode-based detectors that are specially designed for millimeterwave network analyzer applications. With a proprietary circuitry design and careful diode selection, these zero-biased detectors exhibit high sensitivity and extremely flat output characteristics. The below standard offering covers the frequency range of 18 to 170 GHz and offers a 1 MHz video bandwidth and 1 MΩ video output impedance. The standard models also have the capacity to handle a maximum RF input power of up to +17 dBm. The RF interface of these detectors is a standard waveguide with an integrated Faraday isolator to improve the port VSWR. The output voltage polarity is negative and the connector type is a female SMA. Other configurations are offered as custom models.

  • Non-RMS Responding Power Detectors

    Analog Devices Inc.

    Recognized as the pioneer and leader in RF detectors, Analog Devices offers a broad portfolio of high performance logarithmic amplifiers and TruPwr™ rms detectors. ADI logarithmic amplifiers measure signals up to 100 dB dynamic range, from dc to microwave, and accuracies of ±0.2 dB, and are well-suited for both RSSI and transmit power level detection. The TruPwr rms detectors address the challenge of measuring complex waveforms found in spread spectrum CDMA/W-CDMA and higher order QAM modulation systems and provide an accurately scaled dc voltage, which is the rms equivalent of the input waveform.
