VLFX-650+

Overview

The VLFX-650+ is an LTCC low-pass filter with a cutoff frequency of 650 MHz and a bandwidth of 1.025 GHz. It operates at a 50 Ohm impedance with an insertion loss of 1.2 dB. The component provides 40 dB isolation up to 20 GHz. It features SMA connectors and a free-hanging in-line mounting type.

Feature Summary

• Utilizes LTCC technology for signal conditioning
• Provides high isolation rejection up to 20 GHz
• Designed for DC to 650 MHz frequency range

Applications

• RF signal filtering
• Communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet version and connector orientation before procurement. Confirm that the SMA interface matches the system requirements. Ensure the operating temperature range aligns with the application environment. Check for any specific handling instructions regarding the LTCC construction.

Selection Notes

Select this component when a sharp cutoff near 650 MHz is required. The 50 Ohm impedance suits standard RF systems. Consider the 1.2 dB insertion loss impact on signal integrity. The free-hanging design allows for flexible integration into chassis or panel mounts.

Part Context

This part belongs to the VLFX series from Mini-Circuits, specializing in low-pass filters. The series utilizes LTCC technology for compact and reliable performance. These components are designed for applications requiring precise frequency control and high rejection of unwanted signals above the cutoff point.

Replacement Considerations

Consult official Mini-Circuits documentation for direct substitutes. Verify electrical parameters such as cutoff frequency and isolation levels match exactly. Ensure mechanical compatibility including connector type and mounting style before substitution.
