BFHK-4951+

Overview

The BFHK-4951+ is an LTCC band pass filter designed for RF applications, operating within a frequency range of 4300 to 5300 MHz. It features a center frequency of 4.8 GHz and a bandwidth of 1000 MHz. The component maintains a 50 Ohm impedance and exhibits an insertion loss between 3.2 and 4.5 dB. Packaged in a compact NM1812C-3 SMT case style, it utilizes proprietary low-temperature co-fired ceramic material to ensure high performance repeatability and miniature size.

Feature Summary

• Utilizes proprietary LTCC material system for high performance repeatability
• Achieves miniature size suitable for space-constrained designs
• Provides stable signal conditioning with defined passband characteristics

Applications

• RF signal filtering in communication systems
• Signal conditioning in wireless infrastructure
• Integration into compact electronic modules requiring band pass filtering

Procurement Notes

Verify the specific datasheet version and electrical parameter tolerances against current Mini-Circuits documentation before integration. Confirm that the NM1812C-3 package dimensions align with your PCB layout requirements. Ensure that the insertion loss specifications meet your system's signal integrity needs. Cross-reference the center frequency and bandwidth parameters with your application design constraints to guarantee proper functionality.

Selection Notes

Select this component when a fixed center frequency of 4.8 GHz is required with a 1000 MHz bandwidth. Consider the LTCC construction for stability and the SMT package for automated assembly compatibility. Evaluate the insertion loss range against your link budget calculations. Ensure the operating temperature range supports your environmental conditions without additional thermal management.

Part Context

This part belongs to the BFHK series of LTCC band pass filters from Mini-Circuits. The series typically covers frequency ranges from 4.5 GHz to 23.8 GHz. These filters are characterized by high stopband rejection and consistent performance across varying temperatures due to the ceramic substrate technology used in their construction.
