XLF-962+

Overview

The Mini-Circuits XLF-962+ is a reflectionless low-pass filter designed for RF signal paths. It employs a novel topology that absorbs and terminates stop-band signals, eliminating the need for external terminations. The component operates with a cutoff frequency of 12.4 GHz and maintains a 50 Ohm impedance. It features a 2 dB bandwidth specification and is housed in a compact 12-VQFN package with an exposed pad. The device supports an operating temperature range from -55°C to +105°C.

Feature Summary

• Employs a novel reflectionless filter topology that internally absorbs and terminates stop-band signals
• Functions as a low-pass filter with a specified cutoff frequency of 12.4 GHz
• Designed for controlled-impedance RF signal path integration

Applications

• RF signal path filtering in communication systems
• Integration into high-performance S-band upconverters
• Microwave circuit assemblies requiring stop-band absorption

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as XLF-962-DG+ may exist within the product line. Confirm that the required package type matches the 12-VQFN configuration with an exposed pad. Ensure the selected component meets the necessary environmental ratings for the intended operating temperature range. Cross-reference official datasheets to validate electrical specifications against system requirements before procurement.

Selection Notes

Select this component when stop-band signal absorption is required without external termination resistors. The 12.4 GHz cutoff frequency suits applications needing low-pass filtering up to the C-band. The VQFN-12-EP package facilitates surface-mount assembly in space-constrained designs. Verify compatibility with controlled-impedance PCB layouts to maintain signal integrity across the DC to 12.4 GHz passband.

Part Context

The XLF-962+ belongs to Mini-Circuits' family of reflectionless filters, which utilize absorptive topologies to manage out-of-band energy. This approach simplifies circuit design by removing the need for additional termination components typically required in traditional reflective filter architectures. The series targets RF and microwave applications where size reduction and improved stability are critical.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative Mini-Circuits reflectionless filters based on cutoff frequency and package compatibility if substitution is required.
