BPF-A332+

Overview

The BPF-A332+ is a surface-mount lumped LC bandpass filter manufactured by Mini-Circuits. It operates within the 329 MHz to 335 MHz frequency range, providing a center frequency of approximately 332 MHz with a bandwidth of 6 MHz. The component is designed for 50-ohm impedance systems and utilizes an HQ1157 case style package. Key electrical characteristics include linear phase performance, typically maintaining ±5 degrees deviation at frequencies offset by 7.5 MHz from the center frequency. The device supports RoHS and REACH compliance standards.

Feature Summary

• Surface-mount lumped LC construction for compact integration
• Linear phase response with minimal deviation near center frequency
• High rejection characteristics outside the passband

Applications

• RF signal conditioning in communication systems
• Frequency selection in receiver front-ends
• Interference filtering in broadcast equipment

Procurement Notes

Verify the specific ordering suffix and tape-and-reel packaging requirements before purchase. Confirm that the HQ1157 footprint matches your PCB design constraints. Ensure compatibility with 50-ohm system impedance. Check for RoHS and REACH compliance documentation if required by your manufacturing standards. Validate lead times as they may vary based on production schedules.

Selection Notes

Select this component when a narrow 6 MHz bandwidth is required around 332 MHz. The lumped LC topology offers a compact form factor suitable for space-constrained designs. Consider the linear phase characteristic if phase distortion must be minimized. Ensure the operating temperature range meets your application's environmental specifications.
