This low pass filter directional coupler provides -50dB RF sample at the forward and reflected ports. The test ports feature +/- 0.1dB response flatness thanks to a broadband equalizer network. This filter is ideally suited for use with log detectors.
Each filter is carefully sweep tested with our HP8753ES network analyzer.
