Insertion Loss The ratio (in dB) of the power measured at the output port relative to the input port. Directivity The ratio (in dB) of the power measured at the reverse coupled port relative to that measured at the forward coupled port, when the output port is ideally terminated. Flatness The peak to peak variation (in dB) in the coupling factor, over the frequency range. Technical Specifications DCP 0100 Frequency range Power handling (Max.)
