RF filter is an electronic component specially used for processing RF signals, which plays a vital role Its main function is to allow signals within a specific frequency range to pass through, while effectively suppressing or attenuating unwanted frequency components, thereby ensuring the purity and quality of the signal RF filters are widely used in wireless communications, radar systems and other fields, and are key components for achieving signal selection and interference suppression Frequency range: 1090MHz15MHz Filter type: low-pass filter, band-pass filter Input connector: SMA (internal hole external thread) Output connector: SMA (internal hole external thread) Casing: CNC all-aluminum shielding The product appearance and printed words depending on the batch, but this does not affect use.
