Abstract: Systems and methods are provided for generating an amplitude modulation signal to a switchmode power amplifier. A DC to DC switch is configured to receive a DC input voltage and to provide a DC output voltage. A low dropout regulator is configured to provide the amplitude modulation signal according to a modulation control signal received by the low dropout regulator. A control circuit is configured to establish a nominal operating power level for the power amplifier via the amplitude modulation signal and to maintain a minimum voltage difference between the DC output voltage and the low dropout regulator output. A modulator control circuit is configured to provide the modulation control signal to the low dropout regulator. The modulator control circuit provides the transition from a high amplitude to a low amplitude and a transition from the low amplitude to the high amplitude at configurable first and second slopes, respectively.

Abstract: Systems and methods are provided for an antenna coupler mechanism. The antenna coupler mechanism includes a first tuning leg, a second tuning leg, and a bottom plate. The first tuning leg includes a first inductive circuit element, the first tuning leg being configured to accept a radio frequency device in series with the first inductive circuit element. The second tuning leg includes a second inductive circuit element and a capacitive circuit element connected in series, the second tuning leg being connected electrically in parallel with the first tuning leg. In addition, the bottom plate includes a third inductive circuit element connected electrically in parallel with the first tuning leg and connected electrically in parallel with the second tuning leg, the bottom plate being configured to couple energy into a nearby structure.
