Abstract: A technique is described where the switch and/or tunable control circuit for use with an active multi-mode antenna is positioned remote from the antenna structure itself for integration into host communication systems. Electrical delay and impedance characteristics are compensated for in the design and configuration of transmission lines or parasitic elements as the active multi-mode antenna structure is positioned in optimal locations such that significant electrical delay is introduced between the RF front-end circuit and multi-mode antenna. This technique can be implemented in designs where it is convenient to locate switches in a front-end module (FEM) and the FEM is located in vicinity to the transceiver.

Abstract: A system and associated method transfer power between a DC source and a variable load. Two power signals are extracted from the DC source at HF frequency via two self-synchronous radio frequency rectifiers/amplifiers switched by two corresponding HF switching signals having between them either a frequency difference or a phase difference controlled by a duty cycle and overlap controller. The two HF power signals are mixed in a wired, wireless, or bimodal wireless HF power link system to produce a transferred power signal based on the mixing and on manipulating the phase difference when present. A power signal conversion circuit in communication with the HF power link system produces an unfolded output power signal from the transferred power signal. The system and method allow transfer to the load of at least one of an adjustable DC power signal and an AC power signal phase locked to an existing power signal in the load.

Validation detection also occurs when one of the amplitude and the phase of the signal adjusted as a function of the time variation gradient is outside the first thresholds.
