Abstract: A wideband front-end device comprises a wideband amplifying module and a plurality of narrow band filters. The wideband amplifying module comprises an input end, a plurality connecting ends and at least one receiving end. A wideband transmitting RF signal can be transmitted to one of the connecting ends from the input end according to the frequency band thereof. Thus, the wideband transmitting RF signal can be divided into several narrow band signals with different frequency bands. Each narrow band signal with different frequency bands is transmitted to different connecting ends and narrow band filters respectively. Therefore, each narrow band filter can be used to filter wideband transmitting RF signal or narrow band signals with different frequency bands respectively to reduce production costs of the wideband front-end device.

Abstract: A wide band directional coupler comprises a first transmission line, a second transmission line and at least one inductor, wherein the first transmission line and the second transmission line are adjacent each other, and the inductor connects to the second transmission. 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.
