Center frequency: 1575 MHz Outofband suppression: 38 dB Inband fluctuation: less than 1.0 dB Working bandwidth: 20 MHz Key benefits Precise center frequency enables targeted filtering at 1575 MHz to isolate the desired signal and reduce leakage from nearby channels 38 dB outofband suppression minimizes interference from adjacent frequencies, improving overall receiver performance Inband fluctuation less than 1.0 dB provides stable signal level across the passband for consistent modulation and measurement Defined 20 MHz working bandwidth delivers predictable selectivity, aiding compact and reliable frontend design Function, compatibility and performance RF frontend filter designed to operate with a clear 1575 MHz center and a 20 MHz passband, balancing selectivity and signal integrity outofband rejection helps protect sensitive receiver stages from external noise and adjacentchannel interference Stable inband response supports repeatable testing and accurate characterization in lab or field setups 23 use scenarios Use scenario 1: Integrate into an RF receiver frontend or signal path that operates around 1575 MHz to improve channel selectivity and reduce interference Use scenario 2: Employ in a lab measurement setup or test bench to evaluate responses within the 20 MHz window centered at 1575 MHz Use scenario 3: Deploy in a satellite navigation or communication test environment where a stable, narrow passband around 1575 MHz is required for accurate measurements
