VHF-145+

Overview

The VHF-145+ is an LTCC high-pass RF filter manufactured by Mini-Circuits. It operates within a frequency range of 140 MHz to 1.15 GHz, providing a bandwidth of 1010 MHz. The component features a 50 Ohm impedance and utilizes SMA connectors for in-line module termination. It offers low insertion loss with a maximum of 2.0 dB and provides good close-in rejection, including 20 dB attenuation at 115 MHz.

Feature Summary

• Utilizes LTCC technology for compact coaxial construction
• Provides effective stop-band signal rejection
• Maintains low insertion loss across the passband

Applications

• RF signal conditioning
• Radio frequency systems requiring high-pass filtering
• Communication equipment interfacing

Procurement Notes

Verify the specific datasheet version for precise S-parameter measurements and thermal characteristics. Confirm that the SMA connector polarity and mating requirements align with your system interface. Ensure environmental operating conditions meet the component specifications for intended deployment scenarios.

Selection Notes

Select this component when a high-pass response starting at 140 MHz is required. The 50 Ohm impedance matches standard RF transmission lines. Consider the physical dimensions and coaxial form factor for integration into tight spaces where traditional discrete filters may not fit.

Part Context

This part belongs to Mini-Circuits' VHF series of LTCC high-pass filters. These components are designed for applications requiring reliable performance from DC up to microwave frequencies. The series emphasizes small size and robust construction suitable for various RF environments.
