Abstract: A hybrid switched-type phase shifter (STPS) may include the ?-type phase shifters and T-type phase shifters to provide more stable output signals over a wide frequency range. The hybrid STPS may provide output signals based on shifting a phase of the input signal having different frequencies across the frequency range by different phase shifts with relatively similar phase drifts resulting in a reduced phase error during operation. In some cases, the phase shifters discussed above may also include a number of capacitors and/or inductors. In some embodiments, a circuitry or layout of the phase shifters may be shared to reduce a total number of capacitors and therefore reduce a circuit area of the hybrid STPS. Moreover, stacking at least two inductors of the hybrid STPS may also reduce a circuit area for shifting the phase of the input signal by the desired phase shifts across the frequency range.

In active power combiner circuitry, multiple receiving amplifiers may be used to receive radio-frequency signals from the plurality of antennas in the phased antenna array.

Abstract: A temperature fuse assembly for a high-power DC circuit is provided. The temperature fuse assembly includes a case extending from a first case end to a second case end and an isolated lead projecting from the second case end. A bushing electrically isolates the isolated lead from the case.

A portion of the high-gauge wire is helically wound about an exterior of the bushing. When a temperature of the temperature fuse assembly exceeds a threshold temperature, the temperature fuse assembly is configured to conduct a DC current of the high-power DC circuit through the high-gauge wire. The high-gauge wire is configured to melt under a load of the DC current and interrupt the high-power DC circuit.

Abstract: Amplification circuitry is disclosed that couples neutralization transistors to amplification transistors to neutralize parasitic capacitance of the amplification transistors. Gates of a first amplification transistor and a first neutralization transistor are coupled together, and gates of a second amplification transistor and a second neutralization transistor are also coupled together. Drains of the first amplification transistor and the second neutralization transistor are coupled together, and drains of the second amplification transistor and the first neutralization transistor are also coupled together. Sources of neutralization transistors are coupled together at a node, such that a voltage swing of a first signal in the first neutralization transistor may be canceled by a voltage swing of a second signal in the second neutralization transistor.

Abstract: This disclosure is directed to power gain variation compensation of Radio Frequency (RF) receivers based on temperature variations. An RF receiver may include amplification circuitry having a chain of multiple amplifiers and/or passive elements. Multiple distributed and/or lumped attenuators disposed at different points between amplifiers and/or passive elements of the chain may attenuate a received RF signal to compensate for gain variations of the multiple amplifiers and/or passive elements caused by a temperature change. Accordingly, the distributed and/or lumped attenuators may improve linear response of the amplifiers and/or passive elements and signal-to-noise and distortion ratio of RF signals received at the receiver.

The cellular base station may provide the beam configuration information to the wireless device.

Abstract: Configuration management of devices from multiple vendors using a hardware abstraction capability is provided. Abstraction between a high-level representation and vendor specific terminology may assist in translating configuration commands and operational status indicators to a single consistent presentation interface.

Similarly, configuration commands may initially be provided without regard to vendor specific syntax. Utilizing the high-level abstracted representation, a user interface representation of operational status (without regard to vendor terminology) may be provided for a heterogenous rack of associated components from at least two different vendors. Collected data may be analyzed to provide predicted failure of components.

Upon detection of the uniquely identified future device being communicatively coupled to a management network, the previously defined configuration may be applied. Abstraction from a high-level to vendor specific configuration commands may also be incorporated to allow management of devices from multiple vendors.

Abstract: A phased-array receiver is adapted so as to be fully integrated and fabricated on a single silicon substrate. The phased-array receiver is operative to receive a 24 GHz signal and may be adapted to include 8-elements formed in a SiGe BiCMOS technology. The phased-array receiver utilizes a heterodyne topology, and the signal combining is performed at an IF of 4.8 GHz. The phase-shifting with 4 bits of resolution is realized at the LO port of the first down-conversion mixer. A ring LC VCO generates 16 different phases of the LO. An integrated 19.2 GHz frequency synthesizer locks the VCO frequency to a 75 MHz external reference. Each signal path achieves a gain of 43 dB, a noise figure of 7.4 dB, and an IIP3 of ?11 dBm. The 8-path array achieves an array gain of 61 dB, a peak-to-null ratio of 20 dB, and improves the signal-to-noise ratio at the output by 9 dB.
