BPF-A120+

Overview

The BPF-A120+ is a surface-mount bandpass filter manufactured by Mini-Circuits, designed for RF signal conditioning. It operates with a center frequency of 120 MHz and provides a bandwidth of 40 MHz, covering the range from 100 to 140 MHz. The component features a 50 Ohm impedance and utilizes SMD/SMT termination styles within a shielded package. It is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Shielded surface-mount construction for electromagnetic interference protection
• Precise 50 Ohm impedance matching for standard RF systems
• Fixed center frequency filtering at 120 MHz

Applications

• RF receiver front-end filtering
• Signal integrity maintenance in communication modules
• Harmonic suppression in transmitter chains

Procurement Notes

Verify the specific datasheet version when sourcing, as Mini-Circuits may update mechanical dimensions or electrical tolerances over time. Confirm that the SMD footprint matches the PCB design, specifically noting the 14-pin configuration. Ensure environmental ratings meet the target application's thermal requirements, particularly regarding the maximum operating temperature limit.

Selection Notes

Select this component when a fixed 120 MHz center frequency with 40 MHz bandwidth is required. The shielded SMD package is suitable for space-constrained designs needing isolation. Consider the -40°C to +85°C temperature range for industrial or commercial environments. Verify insertion loss specifications against system link budget requirements before finalizing the design.

Part Context

This part belongs to Mini-Circuits' passive RF filter portfolio, which includes various bandpass, low-pass, and high-pass options. The company specializes in components supporting frequencies up to 40 GHz. The BPF series typically employs LTCC or similar technologies to ensure stable performance across wide temperature ranges while maintaining compact form factors for modern electronics.

Replacement Considerations

Consult official Mini-Circuits documentation for direct substitutes. Alternative models may offer different center frequencies or bandwidths but must maintain 50 Ohm impedance and compatible SMD packaging for pin-to-pin compatibility.
