Overview
The BLP-150+ is a coaxial lumped LC low-pass filter manufactured by Mini-Circuits. It provides a passband from DC to 140 MHz with a 50 ohm impedance. The device features a BNC connector interface and operates within an environmental rating of ENV28. Key electrical specifications include a cutoff frequency (fco) of 140 MHz, achieving 20 dB rejection at frequencies between 210-300 MHz. The Voltage Standing Wave Ratio (VSWR) is specified at 1.7:1.
Feature Summary
- Coaxial lumped LC construction for signal conditioning
- Integrated BNC connector for in-line module application
- Rugged shielded case design
Applications
- Test equipment
- Laboratory use
- Transmitters and receivers
- Defense communications
Procurement Notes
Verify the specific datasheet version and revision date when sourcing this component. Confirm that the BNC connector type matches your system requirements. Ensure the environmental rating meets operational standards. Cross-reference part numbers to distinguish between plug-in and coaxial variants within the same family.
Selection Notes
Select this model for applications requiring a fixed 140 MHz cutoff frequency. The coaxial form factor suits systems needing direct BNC integration without additional adapters. Consider the lumped LC topology for cost-effective filtering solutions where physical size constraints are moderate compared to distributed designs.
Part Context
This component belongs to the Mini-Circuits BLP series of coaxial low-pass filters. It shares functional similarities with other models in the lineup but differs in cutoff frequency and package style. The series is designed for general-purpose RF signal conditioning across various industrial and communication sectors.
Replacement Considerations
The PLP-150+ is a plug-in variant with identical electrical performance but different packaging. Verify connector compatibility before substitution. Other BLP series models offer different cutoff frequencies; ensure the spectral requirements match the replacement part.
