Abstract: A mesh network includes multiple in-band on-channel (IBOC) transceivers, connected in a mesh configuration. A first IBOC transceiver communicates directly with a second IBOC transceiver, and an edge transceiver communicates directly with the second IBOC transceiver, but indirectly with the first IBOC transceiver via the second IBOC transceiver. The first IBOC transceiver includes a first network interface, an IBOC radio frequency (RF) transmitter, and a wireless network interface. The first network interface receives broadcast content for IBOC transmission from the edge transceiver. The IBOC RF transmitter transmits the broadcast content within an IBOC broadcast area. The wireless network interface receives feedback, related to the broadcast content, from an IBOC user device within the IBOC broadcast area, and transmits the feedback indirectly to the edge transceiver.

Abstract: A solid state power amplifier uses a Doherty power amplifier that can be implemented as a monolithic microwave integrated circuit. By adjusting the DC bias of the amplifying stages in each branch of the Doherty amplifier, the output power, linearity, and DC power can be adjusted to provide a specified output, where the specification for the output can include the maintaining of desired DC power and linearity. The Doherty power amplifier can be used in a satellite payload or other application utilizing solid state power amplifiers, while providing the proper amount of RF output power and DC power. A single amplifier can have its bias levels adjusted for different output levels, helping to minimize the number of designs that are required for a given satellite payload, reducing the variety of parts in a satellite payload.

Abstract: This disclosure describes techniques for identifying and mitigating a voltage loss in a power transmission to a Remote Radio Unit (RRU) associated with Radio Frequency (RF) antennas of a telecommunications network. More particularly, a Supplemental Voltage (SV) controller is described that is configured to monitor and detect a change in voltage that occurs during a power transmission from a primary Direct Current (DC) power source to the RRU and selectively cause a supplemental DC power source to transmit a supplemental voltage to the RF antennas.

Further, the SV controller may determine whether the primary DC power source has suddenly ceased transmitting power to the RRU, and in doing so, cease transmission of a supplemental voltage to the RRU.
