BPF-B157+

Overview

The Mini-Circuits BPF-B157+ is a surface-mount lumped LC bandpass filter designed for RF applications. It operates with a center frequency of 157 MHz and provides a bandwidth of 12 MHz, covering a passband from 151 to 163 MHz. The component features a 50-ohm impedance and is housed in a compact 6-SMD, no-lead package measuring 20.98mm x 11.99mm x 5.59mm. It supports storage temperatures ranging from -65°C to 150°C.

Feature Summary

• Utilizes lumped LC technology for precise bandpass filtering characteristics
• Designed for surface-mount installation in space-constrained PCB layouts
• Maintains 50-ohm system impedance for standard RF interface compatibility

Applications

• RF signal conditioning in communication systems
• Frequency selection in receiver front-ends
• Interference rejection in wireless infrastructure

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct packaging and tolerance specifications. Confirm that the 6-SMD footprint matches the target PCB design before procurement. Check current availability status as lead times may vary based on manufacturing schedules and regional distribution channels.

Selection Notes

Select this component when a fixed 157 MHz center frequency with 12 MHz bandwidth is required. Ensure the application environment remains within the specified storage temperature range. Verify that the physical dimensions fit the available board space and that the surface-mount package aligns with the assembly capabilities.

Part Context

This part belongs to the Mini-Circuits BPF series of RF filters. It is specifically engineered as a bandpass filter using lumped LC elements. The device is intended for use in radio frequency circuits where specific frequency bands must be isolated or selected from broader signal spectra.
