Abstract
An electronic device and method are provided. The electronic device includes a directional coupler, a sense pair connected to the directional coupler, and an analog-to-digital converter (ADC) connected to the sense pair. The ADC directly digitizes a signal current received from the sense pair.
Claims20
An electronic circuit, comprising:
- a directional coupler;
- a sense pair connected to the directional coupler;
- and
- an analog-to-digital converter (ADC) connected to the sense pair;
- wherein the ADC directly digitizes a signal current received from the sense pair.
2 more elements
A method, comprising:
- coupling, with a directional coupler, power delivered to an antenna to an input of a sense pair;
- converting, with the sense pair, the delivered power to direct current (DC) currents which indicate a power sensed at ports of the coupler;
- and
- directly digitizing, with an analog-to-digital converter (ADC), the converted currents from the sense pair.
