BPF-A69+

Overview

The BPF-A69+ is a surface-mount bandpass filter from Mini-Circuits, designed for RF signal conditioning. It features a center frequency of 69 MHz with a bandwidth spanning 55 to 83 MHz. The component operates within a standard 50Ω impedance environment and utilizes an 18-SMD no-lead package. This configuration ensures precise frequency selection while maintaining signal integrity in compact circuit layouts.

Feature Summary

• Provides selective bandpass filtering centered at 69 MHz
• Utilizes 18-SMD no-lead surface mount packaging
• Operates with standard 50Ω system impedance

Applications

• RF signal path filtering
• Frequency selection circuits
• Communication equipment front-ends

Procurement Notes

Verify the specific ordering suffix (e.g., URJ or RAV) against the required reel quantity and tape specifications. Confirm that the 18-SMD package dimensions align with the target PCB footprint. Ensure the 69 MHz center frequency matches the design requirements before finalizing the purchase order.

Selection Notes

Select this component when a fixed 69 MHz bandpass response is required. The 55–83 MHz bandwidth defines the passband limits. Consider the 18-SMD package size for space-constrained designs. Verify compatibility with 50Ω systems to ensure proper impedance matching and minimal reflection.

Part Context

This part belongs to Mini-Circuits' passive RF filter portfolio. It serves as a dedicated bandpass solution for narrowband applications. The device complements other Mini-Circuits components like amplifiers and mixers by providing essential frequency discrimination in RF chains.

Replacement Considerations

Check for direct substitutes with identical 69 MHz center frequency and 55–83 MHz bandwidth. Verify pinout compatibility for the 18-SMD package. Ensure replacement parts maintain 50Ω impedance characteristics.
