VLFX-1350+

Overview

The VLFX-1350+ is a low-pass filter manufactured by Mini-Circuits, designed for RF applications. It operates within a frequency range of DC to 1350 MHz and maintains a characteristic impedance of 50 Ohms. The device provides high isolation, specified as 40 dB up to 20 GHz. It utilizes SMA connectors for connection and is constructed using LTCC technology in a rugged unibody package.

Feature Summary

• Provides effective signal filtering with a cutoff at 1350 MHz
• Ensures high isolation performance extending up to 20 GHz
• Utilizes robust LTCC construction for durability

Applications

• RF signal conditioning
• Microwave circuit design
• Communication systems

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may undergo revisions. Confirm that the SMA connector gender configuration matches the system requirements, as inline filters often have distinct male and female variants. Ensure the component meets the required environmental operating conditions for the intended deployment scenario.

Selection Notes

Select this component for designs requiring a sharp cutoff near 1350 MHz with minimal insertion loss in the passband. The 50 Ohm impedance compatibility makes it suitable for standard RF transmission lines. Consider the physical size constraints of the unibody package during PCB layout planning to ensure adequate clearance for the SMA connectors.

Part Context

This part belongs to the VLFX series of low-pass filters from Mini-Circuits, which are characterized by their use of LTCC technology. These components are engineered for stability and performance in microwave frequencies. The series offers various cutoff frequencies, with the VLFX-1350+ specifically targeting applications below 1350 MHz.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified alternatives. Generic equivalents may not match the specific isolation or VSWR characteristics of the original LTCC design.
