A switcher to connect the phase shifter and the VGA to each transmitting element in the array. Wherein at most one transmitting element is connected to the phase shifter and the VGA at a given point of time, such that the switcher is a single-pole-M-throw (SPMT) analog switch.

摘要： A method includes, in a receiver, receiving a signal carrying data using multiple antennas, so as to produce multiple respective input signals. The input signals are divided into two or more subsets. The input signals within each of the subsets are combined in a first diversity-combining stage, to produce respective intermediate signals. In a second diversity-combining stage, the intermediate signals are combined to produce an output signal. The output signal is decoded so as to reconstruct the data carried by the received signal.

摘要： The present disclosure relates to digital up-conversion for a multi-band Multi-Order Power Amplifier (MOPA) that enables precise and accurate control of gain, phase, and delay of multi-band split signals input to the multi-band MOPA. In general, a multi-band MOPA is configured to amplify a multi-band signal that is split across a number, N, of inputs of the multi-band MOPA as a number, N, of multi-band split signals, where N is an order of the multi-band MOPA and is greater than or equal to 2. A digital upconversion system for the multi-band MOPA is configured to independently control a gain, phase, and delay for each of a number, M, of frequency bands of the multi-band signal for each of at least N−1, and preferably all, of the multi-band split signals.

摘要： A quadrature detector quadrature-detects an FM signal. An FM detector generates a detection signal by FM detecting an FM signal that has been quadrature-detected. An AFC unit generates a control signal for controlling a frequency of a local oscillation signal used for quadrature detection on the basis of the generated detection signal, and feeds back the control signal to a local oscillator that should output the local oscillation signal. A difference calculator generates a difference signal representing a difference from a reference value on the basis of the generated detection signal. An addition unit adds the generated difference signal and the generated detection signal.

The apparatus includes a first transition counter configured to count a number of bit transitions in a first sequence of one-bit values provided by a first sigma-delta modulator based on the in-phase component, and a second transition counter configured to count a number of bit transitions in a second sequence of one-bit values provided by a second sigma-delta modulator based on the quadrature component. The apparatus further includes a gain monitor configured to: (1) determine a first and second power level, proportional to a power of the in-phase and quadrature components respectively, using the number of bit transitions in the first and second sequences, and (2) adjust a gain of one of the in-phase and quadrature components based on a ratio between the first and second power levels.
