PMI Model Number TD-218-RB is a Threshold Detector optimized for the 2 to 18GHz frequency range. It has an internally fixed threshold level providing a minimum signal level of -30dBm and a maximum input VSWR of 2.75:1. The threshold setting stability is constant ± 3.0 dB over the operating temperature and frequency.
