WR-28 Waveguide Detector

STD-28SF-NI is a Ka Band waveguide detector that covers the frequency range of 26.5 to 40 GHz. The detector is zero biased and intended for small signal detection and network analyzer applications. Due to the proprietary circuitry design and careful diode selection, the detector exhibits high sensitivity and extremely flat output characteristics. The detector is designed to have a 10 MHz video bandwidth and a 1 milliohm video output impedance. The minimum detectable signal level is approximately -50 dBm. A Faraday isolator is integrated to improve the input port return loss
