XLF-962+ Reflectionless Low Pass Filter Datasheet Summary

General Description

The XLF-962+ is a reflectionless low pass filter designed by Mini-Circuits. It employs a novel filter topology that absorbs and terminates stop band signals internally, preventing them from reflecting back to the source. This unique feature enables the filter to be used in applications that require high dynamic range and minimal interference, such as harmonics rejection, satellite, radar, and military & space applications.

Key Features

• Reflectionless Technology: Absorbs unwanted signals, preventing reflections back to the source.
• 50Ω Match in Stopband: Maintains good impedance matching in the stopband, allowing integration with high gain, wideband amplifiers.
• Excellent RF Performance Repeatability: Fabricated on a GaAs process, ensuring consistency for large-volume production.
• Excellent Stability over Temperature: ±0.3 dB variation over temperature, suitable for wide temperature range applications.
• Excellent Power Handling in a Compact Package: High power handling capability in a small 3 x 3 mm package.
• Protected by US Patent No. 8,392,495.
