  • Publication number: 20210028862
    Abstract: Techniques for implementing an internal optical communication link in a power amplifier system are disclosed. In one embodiment, the techniques may be realized as a power amplifier system that includes a panel, an optical link, and a controller. The panel includes a plurality of signal endpoints and a first optical interface, the first optical interface being coupled to each of the plurality of signal endpoints. The optical link is coupled to the first optical interface. The controller is configured to manage operation of the power amplifier system and is coupled to the optical link via a second optical interface. The controller communicates with each of the plurality of signal endpoints over the optical link.

  • Publication number: 20200366258
    Abstract: Techniques for controlling the output of a power amplifier are disclosed. In one embodiment, the techniques may be realized as a system that includes a power amplifier and a controller coupled to the power amplifier to form a feedback loop. The power amplifier is enabled or disabled in response to a blanking signal. The controller includes an accumulator that stores an accumulated error of the feedback loop. The controller suspends operation of the accumulator when (1) a level of the input signal is below a first threshold for an amount of time that exceeds a second threshold, (2) the blanking signal indicates that the power amplifier is disabled, or (3) both. The controller resumes operation of the accumulator when (1) the level of the input signal is above the first threshold and (2) the blanking signal indicates that the power amplifier is enabled.

  • Patent number: 9007125
    Abstract: In general, an RF power amplifier comprises a controller, a driver, a splitter, a final stage, and a combiner coupled together to function as the RF power amplifier. One or more of the above components are arranged on one or more motherboards, e.g., a printed circuit board (PCB). A heat sink defines a base of the RF power amplifier, and in some embodiments includes at least two grooves formed therein, wherein the electrical components of the splitter and electrical components of the controller fit within one or more of the grooves so that these components can substantially disposed within the heat sink. In some embodiments, a power rail is also provided, and is also disposed substantially within the heat sink. The power rail groove of the heat sink and the carrier of the final stage provide an EMI shield of the power rail.

  • Publication number: 20080219154
    Abstract: The present invention relates to a method of sending data packets from a server to clients via a first data link that has a given error rate. The clients are interconnected by a second data link that has a lower error rate than that of the first link. The server sends all the packets to all the clients over the first link, regardless of the client that is the recipient of each of the packets. A client that detects that it has not received a packet of which it is the recipient over the first link requests the other clients to send said packet to it over the second link. The Invention is particularly applicable for video-on-demand.

  • Patent number: 7260452
    Abstract: A circuit to monitor ac line current through resistors employed to provide a ‘step start’ in a power supply, including means to monitor the current flowing through the step start resistors, comprising a peak detector, a sample and hold circuit, an analog to digital convertor and a microprocessor. The output of the current monitoring circuit may be employed to abort starting if abnormalities are sensed. The circuit may also be used to identify when the step start resistors need longer cooling time, and to continuously monitor current at times other than during starting. A timing circuit is also incorporated, which senses zero crossings of the voltage input to the power supply, so as to control the timing of the current monitoring circuit. The discrete circuits employed may be replaced by either a digital signal processor integrated circuit or a general-purpose computer implementing the same steps in a suitable algorithm.
