BLP-30+

Overview

The BLP-30+ is a lumped LC low-pass filter manufactured by Mini-Circuits, designed for signal conditioning applications. It operates from DC to 32 MHz with a 50 Ohm impedance. The device features a cutoff frequency of 35 MHz and provides rejection of 20 dB at frequencies between 47-61 MHz. It exhibits a Voltage Standing Wave Ratio (VSWR) of 1.7:1. This component is available as a BNC in-line module, facilitating integration into RF systems requiring precise low-frequency filtering.

Feature Summary

• Lumped LC architecture for effective low-pass filtering
• BNC in-line module configuration for easy integration
• 50 Ohm system impedance compatibility

Applications

• RF signal conditioning
• Low-frequency noise suppression
• Base station filtering

Procurement Notes

Verify the specific package type and connector style against the official datasheet before procurement. Confirm that the BNC in-line module form factor matches your system requirements. Ensure the operating frequency range up to 32 MHz aligns with your application needs. Check for RoHS compliance status if required by your manufacturing standards. Cross-reference the manufacturer part number to avoid confusion with similar models.

Selection Notes

Select this component when a fixed low-pass characteristic is required within the 32 MHz bandwidth. Consider the BNC interface if modular connectivity is preferred over surface-mount solutions. Evaluate the VSWR specification to ensure it meets your system's reflection tolerance. Compare the physical dimensions of the in-line module against available space constraints. Verify impedance matching for optimal power transfer in 50 Ohm environments.

Part Context

Mini-Circuits produces a wide range of RF filters, including the BLP series. The BLP-30+ belongs to the lumped LC category, distinct from distributed or ceramic designs. It serves as a specialized solution for lower frequency applications compared to microwave filters. The product line emphasizes reliability and consistent performance across various RF environments.
