THÔNG SỐ KỸ THUẬT
This low pass filter directional coupler provides a DC voltage at the forward and reflected ports. The test ports feature a broadband equalizer network. The equalizer maintains a constant RF level at the diodes across the FM band which results in the same voltage at all frequencies.
Each filter is carefully sweep tested with our network analyzers.
