In radio frequency/microwave or even higher frequency range, various transmission‐line filters have been proposed for frequency selection. Specifically, there is a kind of transmission‐line filters not having source/load inverters. To design them is somewhat difficult, if their physical mechanism is not fully understood. In this paper, the concept of the distributed‐ to lumped‐element equivalence is applied in the synthesis of several microstrip band‐pass filters without source/load inverters. As demonstrated, it can help to reveal the physical mechanism of the filters such as how the resonances are created and coupled. In addition, the distributed‐ to lumped‐element equivalence relations between filter specifications and structural parameters are presented and good initial dimensions are calculated, which will facilitate filter design. Several examples are presented for demonstration.
