1. A method comprising, at a bidirectional circuit:
during an amplification time period:
receiving an RF input signal at an RF signal input terminal;
receiving a DC power input at a DC terminal;
generating an amplified signal based on the RF signal input; and
providing the amplified signal at an RF power terminal; and
during a rectification time period:
receiving an RF power input at the RF power terminal;
rectifying the RF power input to generate a DC power output; and
providing the DC power output at the DC terminal;
wherein the amplification time period does not overlap with the rectification time period.
