Amplitude detectors are GaAs beam lead Schottky diode-based detectors with various RF and DC connector options to suit many different applications. With a distinct 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 is designed to have a 10 MHz video bandwidth, 1 MΩ video output impedance, and an RF input power handling of up to +20 dBm. The relationship of the input power and detected output voltage is square root. A typical input power versus detected output voltage curve of a Ka band detector is shown below. The typical tangential sensitivity of the detector is –45 dBm.
