Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H03F 368

US Classification:

330124R, 330295, 330254

Abstract:

A system is provided for activating gain stages in an amplification module. The system includes an amplification module including a first group of amplifiers. Inverting output ports of each of the first group of amplifiers are coupled to a module inverting output terminal, and non-inverting output ports are coupled to a module non-inverting output terminal. A divider network is provided and is coupled to the input ports of the first group of amplifiers. A second group of amplifiers is also provided. Each amplifier of the second group corresponds to one of the amplifiers in the first group, has an inverting input port coupled to the second module inverting input terminal and to output ports of the divider network, and a non-inverting input port coupled to the second non-inverting input terminal. The inverting output ports of the second group of amplifiers are coupled to the inverting output terminal and non-inverting output ports of the second group of amplifiers are coupled to the non-inverting output terminal.

International Classification:

H03F 368

US Classification:

330124R, 295278

Abstract:

Provided is a system for implementing gain control in an amplification module comprising a first stage amplifier having a number of first stage input and output ports. The first stage amplifier is configured to provide first stage amplification to a received input signal and produce from the amplified input signal a number of output signals. Also included are a number of second stage amplifiers, each having second stage input and output ports, the second stage input ports being respectively coupled to the first stage output ports and being configured to receive the number of output signals. A gain control device is coupled to at least one from the group including the first stage input ports, the first stage output ports, and the second stage output ports. The gain control device is also configured to control a gain of at least one of the first stage amplifier and one or more of the number of second stage amplifiers.

Donald McMullin - Rancho Santa Margarita CA

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H03F 345

US Classification:

330254

Abstract:

Provided is a method and system for producing a drive signal for a current steering amplifier. An exemplary method comprises receiving a supply voltage signal and a differential input signal as a circuit input. A differential amplifier drive signal is produced in response to the received supply voltage signal, the received differential input signal, and the received differential control signal. The received differential input signal is adjusted to a value where magnitudes of negative and positive components of the differential control signal become equal to one another and are within a predetermined amount of a magnitude of the supply voltage signal.

Abstract:

Satellite communications are carried out using the Data Over Cable Interface Specification (DOCSIS). Satellite modems are notified of upstream channel congestion by inserting a congestion notification message in a medium access protocol (MAP) message for the upstream channel. Specifically, the congestion notification message is inserted in an unused field of the MAP message, such as the explicit congestion notification (ECN) field. The MAP message can also carry other characteristics of the upstream channel, including priority threshold, multicast access burst availability, and available bandwidth.
