Abstract
Implementations disclosed describe devices for improving wireless localization and ranging operations. In an example embodiment, a circuit includes a receive chain configured to receive a first signal of a first frequency in a first frequency band. The circuit includes a transmit chain configured to transmit a second signal of a second frequency in a second frequency band. The circuit includes an active reflection circuit coupled between the receive and transmit chains. The active reflection circuit includes a frequency conversion scheme. The frequency conversion scheme is configured to receive an input signal from the RX chain at the first frequency, convert the input signal to an output signal at the second frequency, and provide the output signal to the TX chain.
