ALF-12000+

Overview

The ALF-12000+ is a surface-mount thin-film low-pass filter manufactured by Mini-Circuits. It operates from DC to 12 GHz with a cutoff frequency of 13.95 GHz. The component features a 50-ohm impedance and utilizes a sputtered thin-film process on an alumina substrate. Key electrical specifications include a maximum insertion loss of 1.2 dB. The device is housed in a compact 3-SMD module package, designed for high rejection performance in RF signal conditioning applications.

Feature Summary

• Thin-film construction on alumina substrate using sputtering technology
• Surface-mount SMT design for automated assembly integration
• High rejection characteristics across multiple stopband ranges

Applications

• Military communication systems
• Telecommunications infrastructure
• Broadband wireless systems

Procurement Notes

Verify the specific datasheet version for the ALF-12000+ to confirm exact pinout configurations and mechanical dimensions prior to PCB layout. Ensure that the selected evaluation board, such as the TB-ALF-12000+, matches the required interface standards like 2.92mm connectors for accurate testing. Cross-reference the manufacturer's official documentation to validate the presence of the '+' suffix indicating lead-free compliance and current production status.

Selection Notes

Select this component when a low-pass filter with a 12 GHz passband and 50-ohm system impedance is required. The thin-film technology offers superior consistency compared to discrete LC designs. Consider the 3-SMD package size for space-constrained layouts. Verify that the 1.2 dB insertion loss meets the system noise budget requirements for the intended frequency range up to the 13.95 GHz cutoff point.
