With the driving voltage control module, the transceiving circuit and the RF circuit of the RF mobile communication terminal can be supplied with distinct power voltages each corresponding to the cut-off state, the standby state, and the normal operation state, thereby reducing current consumption and the time taken to reach the normal state from the standby state.

摘要： The present invention relates to an accurate method using laser welding for mounting an optical focusing lens utilized in a semi-conductor laser module for optical transmission and optical amplification through an optical fiber and a laser module so produced. The laser module includes an aligned laser diode, a lens fixture mounting the laser diode, a focusing lens mounted within a lens housing which in turn is mounted by a lens ring to the lens fixture. In the method, the steps include aligning mutual positions between the laser diode and the optical focusing lens in the vertical and horizontal directions so that the magnitude of the optical signal output from the optical fiber is maximized after the distance between the optical focusing lens and the optical fiber is adjusted and fixed to obtain a maximum optical coupling efficiency between the laser diode and the optical fiber. Next a laser-welding step is performed at an interval between the lens housing and the lens ring. The mutual positions between the laser diode and the optical focusing lens are aligned in the vertical and horizontal directions so that the magnitude of the optical signal output from the optical fiber is maximized. Finally a laser-welding step is performed at an interval between the lens fixture and the lens ring.
