摘要：
An apparatus can have a power supply circuit configured to receive, from an antenna, a first signal at a frequency exceeding a GHz, and including a rectifier circuit that is impedance matched to the antenna at the first frequency and that is configured to generate a supply voltage by rectifying the first signal at the first frequency. A signal generation circuit can be configured to use the supply voltage to generate a second signal at as higher frequency and to operate in two different power modes in response to a data signal. A transmitter circuit can be configured to use the supply voltage to create pulse at the higher frequency of the signal and in response to the data signal, and that includes an amplifier circuit configured to receive the data signal and provide an amplification of the data signal to the antenna.
