VLFG-630+

Overview

The VLFG-630+ is a low-pass RF filter manufactured by Mini-Circuits, designed for applications requiring signal integrity within the DC to 630 MHz frequency range. It features a 50Ω impedance and utilizes LTCC technology housed in a rugged unibody construction with SMA connectors. The component offers a 3 dB cutoff frequency of 780 MHz, ensuring effective attenuation above the passband. Key electrical specifications include an insertion loss of 2.74 dB and a power handling capability of up to 3.5W RF input. The physical dimensions are 0.410 inches in diameter by 1.430 inches in length.

Feature Summary

• Utilizes LTCC technology for stable performance across a wide operating temperature range.
• Features rugged unibody construction for durability and reliable signal filtering.
• Provides good impedance matching within the passband to minimize signal reflection.

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in transmitter outputs
• Interference rejection in test and measurement equipment

Procurement Notes

Verify the specific datasheet version for the VLFG-630+ to confirm connector type and mechanical tolerances before integration. Ensure that the required power handling of 3.5W aligns with your system's maximum input levels. Check for RoHS3 compliance status if environmental regulations apply to your deployment. Confirm lead times as standard delivery periods may vary based on manufacturer availability.

Selection Notes

Select the VLFG-630+ when a low-pass filter with a 630 MHz bandwidth and SMA interface is required. Consider its 2.74 dB insertion loss and 3.5W power rating against system requirements. Compare its physical size and mounting style with available space constraints. Evaluate the 780 MHz cutoff frequency to ensure adequate stopband attenuation for your specific harmonic or noise frequencies.
