1. 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.
