Marcello Donati has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9397616
    Abstract: An amplifier including a main amplifier circuit and at least one peaking amplifier circuit. The peaking amplifier circuit is selectively operable to operate in combination with the main amplifier circuit. The main amplifier circuit and the peaking amplifier circuit each include an active device operation as an inverse Class-F amplifier element. The main amplifier circuit and the peaking amplifier circuit also each include a combined matching and resonator network coupled with an output of the respective active device so the active device operates as an inverse Class-F device, and a combined matching and resonator network coupled with an input of the respective active device.
    Type: Grant

  • Patent number: 6993069
    Abstract: A testing system includes simulation equipment for generating a radiofrequency test signal for the receivers of a base transceiver station, which is equipped with an intelligent array antenna having N sensors. The simulation equipment generates a complex signal consisting of N identical radiofrequency signals with differing phases. These signals are conveyed towards N antenna input connectors of the receivers to be tested. The N test signals are obtained by generating as many groups of N digital isofrequential carriers as are required to simulate the directions of a useful signal with an arbitrary number of echoes, and the directions of an arbitrary number of isofrequential interferent carriers. The N carriers of each group are appropriately modulated and digitally multiplied by the same number of relevant beamforming coefficients to produce, within each group, gradually increasing phase values.

  • Patent number: 5311504
    Abstract: A base station in a mobile digital system (TDMA/FDMA) utilizes a frequency hopping technique. The interconnection among receiver/transmitters (RT1-RTm) and process nodal points (NP1-NPm) takes place in base band using a common medium as distribution means of data relevant to the different users, which are entered on and sensed from at least one bus (B, B'). According to one embodiment two separate bus are foreseen, one for transmission and the other one for reception.
