Reflectionless bandpass filter with flat passband, high selectivity, and enhanced out-of-band suppression

Tongxin xuebao
Currently, the design of reflectionless filters was challenged by insufficient selectivity and insufficient flatness. Therefore, a two-port microstrip reflectionless bandpass filter topology was proposed to provide a reference for addressing these ...
