XLF-982+

Overview

The XLF-982+ is a reflectionless low-pass filter manufactured by Mini-Circuits, designed for RF applications up to 13.1 GHz. It employs a novel topology that absorbs and terminates stop-band signals, eliminating reflections. The component operates within a frequency range of DC to 9.8 GHz with a cutoff at 13.1 GHz. It features a 50-ohm impedance and utilizes a 12-VQFN exposed pad package. Electrical specifications include a bandwidth of 1.8 dB, ensuring signal integrity in sensitive circuits.

Feature Summary

• Employs a novel reflectionless topology that absorbs and terminates stop-band signals to eliminate reflections
• Designed for use with sensitive devices requiring minimal signal interference
• Operates as a low-pass filter with defined cutoff characteristics

Applications

• Paired with sensitive RF devices requiring reflectionless performance
• Applications necessitating elimination of stop-band reflections
• RF signal conditioning systems

Procurement Notes

Verify the specific suffix (+ or -DG+) against the required environmental rating and datasheet revision. Confirm the package type matches the design footprint. Ensure the cutoff frequency aligns with system requirements. Cross-reference manufacturer part numbers with distributor listings to avoid counterfeit components. Validate electrical specifications against the latest official documentation before integration.

Selection Notes

Select this component when reflectionless performance is critical for system stability. The absorption of stop-band signals makes it suitable for cascading with sensitive amplifiers or mixers. Consider the 12-VQFN package size for PCB layout constraints. Verify temperature stability requirements against the specified operating range. Ensure the 50-ohm impedance matches the system architecture.

Part Context

This component belongs to Mini-Circuits' XLF series of reflectionless filters. These filters utilize proprietary technology to terminate out-of-band signals internally. The series offers various cutoff frequencies to suit different RF bands. The XLF-982+ specifically targets high-frequency applications requiring precise low-pass filtering without reflected energy.
