摘要： An improved method and apparatus for using parallel amplifiers to efficiently amplify an information signal are disclosed. The improved apparatus utilizes digital signal manipulation techniques in optimizing the phase of the upconverted input signals provided to each of the parallel amplifiers. The phase and amplitude of the input signals are adjusted such that the power measured at the output of a combiner is maximized as compared to the sum of the power of combiner input signals.

摘要： A base station and receiver system for use in a base station which achieves enhanced dependability by logically separating the diversity reception paths into different failure paths. In one embodiment, the receiver system includes a first diversity reception path for receiving a first radio signal and a second diversity reception path for receiving a second radio signal. The first and second radio signals may be amplitude and phase shifted versions of the same information signal according to well known principles of diversity reception. At least one demodulator diversity combines the first and second radio signals and demodulates the diversity combined first and second radio signals. Additionally, the first and second diversity paths are logically separated into different failure paths.

摘要： An oscillator comprises an active device with a phase shift of less than 180 degrees. A first delay line has first and second ends. The first end of the first delay line is coupled to an active port of the active device. A ring mode trap filter is coupled to the second end of the first delay line. A second delay line has first and second ends. The first end of the second delay line is coupled to the ring mode trap filter. The second end of the second delay line is coupled to a resonance means. The total delay of the first and second delay lines allows the resonance means to oscillate at its natural frequency in spite of the less-than-180-degree phase shift of the active device.

摘要： Certain aspects of the present disclosure propose an adaptive joint linear and non-linear digital filter that can adaptively estimate and reconstruct cascaded effects of linear and non-linear self-jamming distortions introduced by non-linearities in the transmit and/or receive chains. The proposed digital filter may be used to cancel second-order inter-modulation distortion (IM2) generated in the receive chain and/or harmonic distortion generated in the transmit chain, as well as other distortions introduced by the transmit/and or receive chains.

摘要： A dielectric resonator probe for measuring surface resistance of a test material, particularly at cryogenic temperature, is provided. A dielectric resonator is mounted near to but spaced from a conductive plate and is positioned in contact with a test material. Preferably, a low-loss dielectric spacer separates the resonator from the upper plate. The dielectric resonator has a larger lower surface area than upper surface area. The dielectric resonator includes a hole therethrough for increasing mode separation and for accommodating a mounting bolt. The mounting bolt is preferably nonconductive and is coupled to a spring for resiliently mounting the resonator and spacer to the plate so as to accommodate differential thermal expansion of the components.

摘要： A method and apparatus for eliminating transmit echo spurs is provided. The method includes the steps of: estimating a distortion effect applied to a transmit signal by a duplexer stop band. Next, the contribution of a primary component of the spur is estimated. An image component of the spur is estimated after the primary contribution has been estimated. The transmit echo is then subtracted from the composite desired signal by digitally subtracting the distortion effect, the primary component of the spur, and the image component of the spur, producing the desired composite transmit signal without the transmit echo.
