Configurable radio frequency filter for multi-band communication
A recently granted patent (Publication Number: US12004134B2) discloses a system comprising three antennas operating in different frequency bands - low-band (600 MHz), mid-band (2500 MHz), and high-band (26 GHz and 28 GHz). The system includes a radio frequency integrated circuit (RFIC), bandpass filters, switches, processors, and computer-readable media storing instructions. The system is designed to receive data indicating channel allocation and send signals to selectively couple the appropriate bandpass filter for communication with a base station using time-division duplexing (TDD). The system can operate in various wireless resources, including Citizens Broadband Radio Service (CBRS), and support carrier aggregated communication using multiple wireless resources.
Furthermore, the patent describes a method associated with the system, involving receiving channel allocation data, sending signals to couple bandpass filters based on the data, and establishing communication between user equipment and a base station. The method includes interactions with a Spectrum Access System (SAS), utilizing different wireless resources for carrier aggregation, and determining the use of specific bandpass filters based on configurable settings. The system and method aim to optimize communication efficiency across different frequency bands, supporting both 4G and 5G operations, and enabling seamless connectivity in diverse wireless environments. The patent highlights the flexibility and adaptability of the system in managing channel allocations and enhancing communication performance for various applications.
