摘要： Disclosed is a bidirectional amplifier. The bidirectional amplifier includes a first matching circuit, a second matching circuit, an amplifier circuit connected between the first matching circuit and the second matching circuit, that amplifies a first input signal received from the first matching circuit to output the amplified first input signal to the second matching circuit, and that amplifies a second input signal received from the second matching circuit to output the amplified first input signal to the first matching circuit, and the first and second matching circuits have a symmetrical structure and operate complementary to each other.

摘要： In one embodiment, a method receives a downstream signal and an upstream signal in a same frequency band. The downstream signal and the upstream signal are separated into a first path and a second path. The downstream signal using the first path and the upstream signal using the second path are amplified in an analog domain. The method isolates the downstream signal and the upstream signal from one another and sends the downstream signal downstream to a subscriber device and sends the upstream signal towards a full duplex node.

摘要： Embodiments describe systems, apparatuses, and methods for transmitting/receiving signal data to/from a plurality of transceiver modules. Devices in accordance with some embodiments can include a plurality of wireless transceiver modules, each wireless transceiver module to be communicatively coupled to a corresponding external transceiver mixture, one or more antennas to exchange signal data with the plurality of external transceiver modules, a radio frequency (RF) circulator, and one or more amplifiers to amplify the signal data received by the one or more antennas and signal data to be transmitted by the one or more antennas. The use of the RF circulator prevents transmitting signals that may collide with each other and cause interference with the communications.

摘要： In a general aspect, a current sense amplifier circuit (CSA) can include a null amplifier path and a main amplifier path that are both configured to receive a differential input voltage. The null amplifier path can output a first differential output voltage based on the differential input voltage. The main amplifier path can also be configured to receive the first differential output voltage and output a second differential output voltage based on the differential input voltage and the first differential output voltage. The null and main amplifier paths can each include a differential amplifier having first and second input stages that are each configured to receive the differential input voltage. The first input stage and the second input stage of the main amplifier path can and be powered by a respective (first and second) floating voltage supply rails that are referenced to a floating ground rail.
