Abstract
An electronic circuitry is proposed. The electronic circuitry comprises a directional coupler comprising a first port configured to receive an input signal from a signal source, a second port configured to output the input signal for transmission to a load, a third port configured to output a forward signal based on the input signal, and a fourth port configured to output a reverse signal based on a reflection of the input signal received at the second port. The electronic circuitry further comprises a Time-to-Digital converter, TDC, coupled to the third port and the fourth port. The TDC is configured to determine a phase difference between the forward signal and the reverse signal.
Claims17
An electronic circuitry comprising:
- a directional coupler comprising:
- a first port configured to receive an input signal from a signal source;
- a second port configured to output the input signal for transmission to a load;
- a third port configured to output a forward signal based on the input signal;
- and
- a fourth port configured to output a reverse signal based on a reflection of the input signal received at the second port;
- an attenuator coupled between the third port and a Time-to-Digital converter, TDC,
- wherein the attenuator is configured to output an attenuated forward signal by attenuating the forward signal based on a power of the forward signal and a power of the reverse signal;
- and
- the TDC, coupled to the third port and the fourth port,
- wherein the TDC is configured to determine a phase difference between the forward signal and the reverse signal based on the attenuated forward signal.
A system comprising:
- a signal source, wherein the signal source is configured to generate an input signal
- an electronic circuitry comprising:
- a directional coupler comprising:
- a first port configured to receive the input signal from the signal source;
- a second port configured to output the input signal for transmission to a load;
- a third port configured to output a forward signal based on the input signal;
- and
- a fourth port configured to output a reverse signal based on a reflection of the input signal received at the second port;
- and
- a Time-to-Digital converter,-TDC, coupled to the third port and the fourth port, wherein at least part of the input signal is clipped, and wherein the TDC is configured to determine a phase difference between the forward signal and the reverse signal based on a part of the forward signal that is based on the clipped part of the input signal.
A method comprising:
- receiving, at a directional coupler, an input signal from a signal source;
- generating a forward signal, by means of the directional coupler, based on the input signal;
- receiving, at a Time-to-Digital Converter, TDC, coupled to the directional coupler, the forward signal from the directional coupler;
- receiving, at the TDC, a reverse signal based on a reflection of the input signal received by the directional coupler at a port for outputting the input signal to a load;
- outputting, by means of an attenuator coupled to the TDC, an attenuated forward signal by attenuating the forward signal based on a power of the forward signal and a power of the reverse signal;
- and
- determining, by means of the TDC, a phase difference between the forward signal and the reverse signal based on the attenuated forward signal.
