Abstract
A device includes, in part, an antenna adapted to receive an RF signal that includes modulated data, a splitter/coupler adapted to split the received RF signal, a receiver adapted to demodulate the data from a first portion of the RF signal, and a power recovery unit adapted to convert to a DC power a second portion of the RF signal. The splitter/coupler is optionally adjustable to split the RF signal in accordance with a value that may be representative of a number of factors, such as the target data rate, the DC power requirement of the device, and the like. The device optionally includes a switch and/or a power combiner adapted to deliver all the received RF power to the receiver depending on any number of operation conditions of the device or the device's distance from an RF transmitting device.
