    摘要: The present invention relates to an integrated device for transmitting and/or receiving information by means of millimetric waves (wavelength 1 mm-10 mm), i.e. electromagnetic waves corresponding to frequencies of 30 to 300 GHz. In particular, the present invention relates to a device constituted by an optoelectronic integrated circuit that interfaces with an antenna able to transmit and/or receive millimetre wave signals. In turn the device, associated to the appropriate biasing and control electronics, constitutes a transceiver module to be used in a wireless or mobile radio local area network. rhe transmitter circuit is constituted by a laser in passive mode-locking. The optical signal thus generated is amplified, modulated and converted into radio frequency signal through a guide photodiode, to be lastly transmitted through an antenna. The receiver circuit is constituted by an antenna, a photodiode and a laser identical to that of the transmitter. The photodiode, by means of appropriate bias, performs a dual function of optical and electrical mixer. In particular, the first function converts to electrical frequency the optical beat signal between two modes generated by the laser, the second function takes place by means of the non linear voltage/current characteristic of the photodiode and allows to bring back to base band the received signal, thereby allowing to extract the modulating signal from the weak signal received through the antenna.

    摘要: A method of and an apparatus for measuring return loss in an optical fiber component. Radiation of a predetermined wavelength, e.g. from a laser, is launched into an optical fiber component, preferably through an optical fiber having a polarization control loop and the radiation reflected and the direct radiation are subjected to phase modification. An amplitude of the frequency component of the detected signal at the frequency imposed by phase modulation is measured and is used as the basis for evaluating the return loss.

    摘要: A wireless communication terminal includes a SIM card and a memory card equipped with respective radio transceivers for allowing a terminal-independent and network-independent radio communication between both cards. Server and client applications on the controllers of the transceivers allow the SIM to manage the memory card. The memory card tries to become connected to the SIM. If connection is successful, the SIM authenticates the memory card and then configures it, in secure mode, to set the access policy to the memory card itself.
