[0002] L-band refers to a radio wave band with a frequency range of 2 GHz (or sometimes 1.5 GHz). This band is widely used in wireless communication systems (such as base stations, relay stations, etc.), radar systems, satellite communication systems and other fields. A broadband filter is an electronic component that allows frequency signals within a certain range to pass through while suppressing other frequency signals. A 200W broadband filter can handle a power of up to 200W and is suitable for high-power transmission systems. L-band 200W broadband filters generally use low-temperature co-fired ceramic (LTCC) technology or multi-layer coupling structure technology, and in order to achieve high-power and wide-bandwidth filters, high-precision manufacturing processes are required to ensure the performance and stability of the filter.
