BFCG-1902+

Overview

The BFCG-1902+ is an LTCC bandpass filter designed for mmWave frequencies, featuring a center frequency of 18.6 GHz and a bandwidth of 3.4 MHz. It operates within a passband range of 17 to 20.4 GHz with a nominal insertion loss of 2.5 dB. The component supports up to 1W RF input power and functions across a wide temperature range from -55°C to +125°C. Packaged in a compact 0805 (2012 Metric) surface-mount case style, it ensures high performance repeatability.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for miniature size and high performance repeatability at mmWave frequencies.
• Designed for dense PCB applications with robust thermal stability across a wide operating temperature range.
• Provides effective EMI/RFI suppression suitable for power line filtering and signal integrity maintenance.

Applications

• EMI/RFI suppression
• Power line filtering
• Dense PCB integration

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as Mini-Circuits may offer different mechanical or electrical configurations under similar part numbers. Confirm that the required center frequency and bandwidth align precisely with your circuit design specifications before finalizing procurement. Ensure compatibility with standard SMT assembly processes given the 0805 footprint.

Selection Notes

Select this component when a narrow bandwidth around 18.6 GHz is required for mmWave applications. Consider the 1W power handling capability and the -55°C to +125°C temperature range for harsh environments. The 0805 package makes it suitable for space-constrained designs requiring high-frequency filtering without compromising board density.

Part Context

This component belongs to the BFCG series of LTCC bandpass filters from Mini-Circuits. The series is engineered for RF and microwave applications, offering consistent performance from DC to high frequencies. These filters are characterized by their small form factor and reliability, making them staples in modern communication systems requiring precise frequency selection.

Replacement Considerations
