Mini-Circuits BFCN-1945+ Environmental and export classification status description

The Mini-Circuits® BFCN-1945+ is a broadband RF band-pass filter designed to operate with a nominal passband centered around 1945 MHz. It is constructed to suppress unwanted frequencies and allow signals in its designated frequency range to pass with minimal loss and distortion. The filter is commonly used in various RF applications, providing effective performance for communication systems. Functions - Band-Pass Filtering: Allows signals within a specific frequency band to pass while attenuating signals outside this band. - Impedance Matching: Designed to maintain a 50-ohm system impedance to enhance signal transfer and minimize reflections. - Signal Conditioning: Helps in enhancing the quality of received signals by reducing noise and interference from adjacent channels. Applications - Wireless Communication Systems: Used in cellular base stations, mobile communication devices, and satellite communication. - Test and Measurement Equipment: Helps in signal analysis and measurement setups where specific frequency components need to be isolated. - Broadcasting: Employed in TV and radio broadcasting for selective frequency filtering. Alternative Parts - Mini-Circuits® BFCN-1925+: A similar band-pass filter with a slightly different center frequency. - Mini-Circuits® BPF-1940+: Another alternative option for filtering applications in the 1940 MHz range. - RFMW® RF Filter Options: Various other manufacturers provide comparable band-pass filters based on the specific requirements. Embedded Modules Mini-Circuits® also offers integrated solutions combining multiple functions and filters within a single module. This provides a compact solution for more complex systems needing filtering in conjunction with amplification or other signal processing. Q&A 1.
