摘要： Detecting an imminent failure of a power supply. The power supply may supply power to an Optical Line Terminal (OLT) node, an Ethernet switch, a Community Access television (CATV) plant, an optical node, a smart optical node, an outdoor Wi-Fi hot-spot, an 802.11n Wi-Fi Access Point, a wireless base station, and a Digital Subscriber Line Access Multiplexer (DSLAM). An internal computerized component periodically reads a set of measurements from one or more sensors affixed to a power supply. The internal computerized component and power supply may reside in a variety of different technical contexts. The internal computerized component analyzes the set of measurements using, at least in part, a weighted set of factors, to detect the imminent failure in the power supply. The weighted set of factors may be updated or revised over time and may be specifically tailored for use with specific types of power supplies.

摘要： Dynamic adjustment of the power amplifier bias of a power amplifier. Circuitry, disposed within an apparatus, measures the power level presently being handled by the power amplifier. The circuitry adjusts the power amplifier bias for a power amplifier based on the measurement of the power level presently being handled by the power amplifier and a desired fidelity experienced by RF signals processed by the power amplifier. The adjustment in the power amplifier bias for the power amplifier causes an adjustment in a power consumption of the power amplifier, thereby enabling great saving in the DC power required by a power amplifier, and thus, substantially reduces the power consumption of the apparatus in which it operates, such as a Remote PHY node, a Remote MACPHY node, a HFC RF amplifier, a wireless communication device, cellular transmission equipment, or a satellite transponder, for example.

摘要： Increasing an analog to digital converter (ADC) dynamic range for a communications device. In the communications device, a reference threshold is established for a peak to average power ratio (PAPR) improvement factor for RF signals received by the communications device. A digital to analog converter (DAC) adjustment factor is established for a DAC to account for inaccuracies of a pre-cancellation DAC and fine tuning of an analog gain of received RF signals. A peak amplitude separation element evaluates an absolute value of a portion of a particular RF signal against the reference threshold. Upon the peak amplitude separation element determining that the portion is smaller than the reference threshold, the element assigns a zero value to a DAC signal current sample; otherwise, the element assigns a quantized value of the sample to the DAC signal current sample, used in adjusting a post-cancellation signal sample.

摘要： Performing distributed Remote PHY scheduling operations. A low latency scheduler is disposed within or in proximity to a Remote PHY node. Upon identifying that a particular data flow qualifies for processing by the low latency scheduler, the low latency scheduler performs upstream Remote PHY scheduling operations for the particular data flow using a one or more dedicated channels that are designated as low latency channels. The Remote PHY upstream scheduling operations define when data may be transmitted by a Cable Modem (CM) to a Converged Cable Access Platform (CCAP) Core. A centralized scheduler is also located at the CCAP Core. The centralized scheduler performs Remote PHY upstream scheduling operations for all data flows which have not been identified as qualifying for processing by the low latency scheduler.

摘要： A directional coupler having coupling variability at separate portions of an operational frequency band. The coupler may be comprised within a Full Duplex (FDX) amplifier and itself may comprise input and output ports, a coupled port, a termination port, a first RF filter coupled to the coupled port, and a second RF filter coupled to the termination port. The first and second RF filters yield a first coupling value at one portion of the operational frequency band of the coupler and a second coupling value at a second portion of the operational frequency band. The first portion of the band corresponds to a range of frequencies at which higher coupling for the coupler is desired and greater loss in the signal is tolerable. The second portion of the band corresponds to a range of frequencies at which lower coupling for the coupler is tolerable and lower signal loss is desirable.

摘要： Preventing RF signal distortion and signal error producing memory events in a Radio Frequency (RF) power amplifier (RFPA). An element, disposed prior to the Radio Frequency (RF) power amplifier (RFPA) in a signal path of a RF signal input to the RFPA, may enforce a maximum allowable amplitude in a high PAPR instantaneous high peak of the RF signal. An element may also increase or supplement a bias of the Radio Frequency (RF) power amplifier (RFPA) when a high PAPR instantaneous high peak is detected in the RF signal prior to receipt by the RFPA. Additionally, a first element operable detects when an instantaneous output voltage of the Radio Frequency (RF) power amplifier (RFPA) is below a predetermined voltage, and in response, a second element supplies additional current to prevent the output voltage of the RFPA from falling below a predetermined threshold voltage.

摘要： Approaches for compensating for RF imperfections in a system that comprises two or more independent modules. The two or more independent modules may be comprised within a remote PHY node (RPN). RF calibration data is stored in one or more non-volatile mediums for two or more independent modules. Each of the two or more independent modules are electronically coupled in a sequence via a transmission medium. A first independent module digital compensates a RF signal for a set of two or more modules that are coupled together in sequence via the transmission medium. The first independent module may correspond to a remote PHY device (RPD).
