BFCN-1525+

Overview

The BFCN-1525+ is a surface-mount bandpass filter from Mini-Circuits, designed for signal conditioning applications. It operates at a center frequency of 1.525 GHz with a bandwidth of 90 MHz. The component features a 50 Ohm impedance and utilizes LTCC technology for ruggedness in high-humidity and high-temperature environments. Key electrical specifications include an insertion loss of 3 dB. It is housed in a compact 1206 (3216 metric) package with SMD/SMT termination. The device supports board mounting and functions within a temperature range of -55°C to +100°C.

Feature Summary

• Constructed using multilayer ceramic technology for miniature size and high repeatability
• Wrap-around terminations minimize performance variations due to parasitics
• Provides low insertion loss and good rejection at band-reject edges
• Rugged package suitable for tough environments including high humidity and temperature extremes

Applications

• Signal conditioning circuits
• RF front-end filtering
• Space qualified RF systems

Procurement Notes

Verify the specific datasheet version for the BFCN-1525+ to confirm exact electrical tolerances and mechanical dimensions before integration. Ensure compatibility with the target PCB layout regarding the 1206 footprint and soldering profile. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market. Confirm that the operating temperature range aligns with the environmental conditions of the final assembly.

Selection Notes

Select this component when a compact, rugged bandpass filter is required for the 1.525 GHz frequency range. The LTCC construction offers advantages in harsh environments compared to standard ceramic filters. Consider the 3 dB insertion loss and 90 MHz bandwidth against system sensitivity and channel spacing requirements. The 50 Ohm impedance matches standard RF transmission lines, simplifying circuit design without additional matching networks.

Part Context

This part belongs to the BFCN series of LTCC bandpass filters manufactured by Mini-Circuits. The series is characterized by its use of low-temperature co-fired ceramic technology, which enables small form factors and reliable performance. These filters are typically used in wireless communication systems where space constraints and environmental durability are critical design factors.
