VLF-1000+

Overview

The VLF-1000+ is an LTCC low-pass filter designed for RF applications, operating from DC to 1000 MHz with a 50-ohm impedance. It features SMA connectors and utilizes Mini-Circuits' proprietary LTCC technology for compact surface-mount integration. The component provides high rejection at stopband frequencies, ensuring signal integrity in broadband systems.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for robust construction
• Provides effective attenuation of frequencies above the 1000 MHz cutoff
• Designed for surface-mount installation with standard SMA interfaces

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in transmitter outputs
• Anti-aliasing filtering in data acquisition circuits

Procurement Notes

Verify the specific datasheet revision and connector type upon ordering, as physical configurations may vary. Confirm that the LTCC package style matches your PCB footprint requirements. Ensure environmental ratings align with your operational temperature range before finalizing procurement.

Selection Notes

Select this component when a compact, broadband low-pass filter is required up to 1 GHz. Consider the LTCC construction for superior thermal stability compared to traditional ceramic filters. Evaluate insertion loss and stopband rejection specifications against system noise floor requirements.

Part Context

This part belongs to Mini-Circuits' VLF series of low-pass filters. It represents a transition from discrete components to integrated LTCC modules, offering improved consistency and smaller form factors for modern RF circuit designs requiring precise frequency control.
