Tunable Non-Reflective Band-Reject Filter (700MHz-1GHz)

SPCL-00597 - K&L Microwave (Dover Corp)

This device is placed after the DUT to protect the Spectrum Analyzer from high-power fundamentals and provide harmonic measurements. The non-reflective functionality prevents energy from bouncing back to the DUT and raising the noise floor level.
Broadband matching improves dynamic range and reduces
measurement uncertainty.
