VHF-650+

Overview

The VHF-650+ is an LTCC high-pass filter manufactured by Mini-Circuits, designed for RF signal conditioning applications. It features a cutoff frequency of 650 MHz and operates within a bandwidth of approximately 1.78 GHz to 1.79 GHz. The component utilizes SMA connectors in an inline module configuration and maintains a standard impedance of 50 Ohms. Typical insertion loss is specified at 3.57 dB. The device supports frequency ranges extending from 710 MHz up to 2490 MHz or 2000 MHz depending on the specific datasheet reference, ensuring effective attenuation of lower frequencies while passing higher signals.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for robust construction
• Provides high-pass filtering characteristics with defined cutoff frequency
• Features SMA connector interface for direct integration into RF systems

Applications

• RF signal conditioning in communication systems
• Interference suppression in radio frequency circuits
• High-frequency signal processing modules

Procurement Notes

Verify the exact datasheet version when ordering, as specifications such as bandwidth and frequency range may vary slightly between revisions. Confirm that the SMA connector type matches your system requirements. Ensure compatibility with 50 Ohm impedance networks. Check RoHS compliance status if required for your manufacturing process. Validate insertion loss tolerances against your specific application needs before finalizing procurement.

Selection Notes

Select this component when a high-pass filter with a 650 MHz cutoff is required. Consider the LTCC construction for stability in various environments. Evaluate the insertion loss of 3.57 dB against system power budgets. Ensure the SMA inline package fits your mechanical constraints. Compare performance across the 710 MHz to 2490 MHz range to confirm suitability for your target frequency band.
