As a RF signal passes through the first transmission line, the second transmission line will couple with the RF signal in the first transmission line to generate a coupling signal. The inductor is connected to the second transmission line to improve the coupling factor and/or the insertion loss of the wide band directional coupler at high frequency band. | 01-28-2016 |
