BPF-BD1400+

Overview

The BPF-BD1400+ is a lumped LC bandpass filter manufactured by Mini-Circuits, designed for RF signal conditioning applications. It operates within a passband frequency range of 1200 MHz to 1600 MHz, providing a center frequency of 1400 MHz with a 400 MHz bandwidth. The component maintains a standard impedance of 50 ohms and utilizes surface mount technology (SMT) for integration into printed circuit boards. Constructed with high Q-factor elements, the filter ensures effective frequency selection and harmonic suppression in microwave circuits.

Feature Summary

• Utilizes lumped LC topology for precise bandpass filtering characteristics
• Employs surface mount technology (SMT) for compact PCB integration
• Features high Q-factor construction for improved signal selectivity

Applications

• RF signal conditioning in wireless communication systems
• Frequency selection in S-band upconverter assemblies
• Harmonic suppression in RF test equipment
• Interference filtering in IoT terminals

Procurement Notes

Verify the specific ordering suffix to ensure compliance with RoHS and REACH standards as indicated in official documentation. Confirm that the required package style matches the TV2849 case specification provided in the datasheet. Cross-reference the part number with the manufacturer's current product list to validate availability status and confirm that no alternative packaging options are required for the intended manufacturing process.

Selection Notes

Select this component when a fixed 1200-1600 MHz passband is required for 50-ohm systems. The lumped LC design offers a compact form factor suitable for space-constrained layouts. Ensure that the application does not require tunable frequency response, as this model provides a static bandpass characteristic optimized for stable performance across the specified frequency range without external adjustment mechanisms.

Part Context

This component belongs to Mini-Circuits' passive RF filter portfolio, specifically the bandpass category. It complements other signal chain components such as amplifiers and mixers used in complete RF subsystems. The device supports one-stop hardware design methodologies by providing reliable frequency definition within broader microwave architectures, contributing to overall system signal integrity and noise reduction.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing board layouts if considering alternatives, as package dimensions and pin configurations may differ significantly between manufacturers or even within different Mini-Circuits series.
