Abstract

An apparatus comprises a system on a chip (SoC). In some embodiments, the SoC includes a power supply circuit, a power management circuit operatively coupled to the power supply circuit, a first wireless communications circuit and a second wireless communications circuit. The first wireless communications circuit is configured to receive an RF signal and is operatively coupled to the power supply circuit and the power management circuit. The first wireless communications circuit has a net radio frequency (RF) power gain no more than unity before at least one of downconversion of the RF signal or detection of the RF signal. The second wireless communications circuit is operatively coupled to the power supply circuit and the power management circuit.
