摘要

A device comprising: a substrate; a semiconductor die mounted on the substrate; a transmit antenna fabricated on the substrate and configured to transmit radio-frequency (RF) signals at least at a first center frequency; a receive antenna fabricated on the substrate and configured to receive RF signals at least at a second center frequency different than the first center frequency; and circuitry integrated with the semiconductor die and configured to provide RF signals to the transmit antenna and to receive RF signals from the receive antenna.

說明書

The target device 915 may be manufactured in any of the ways described herein including in any of the ways described with reference to target device 900. For example, in some embodiments, the target device 915 may comprise a substrate having the receive antenna 122 and transmit antenna 126 fabricated thereon, and a semiconductor die mounted to the substrate, coupled to the receive and transmit antennas, and having signal transformation circuitry 124b fabricated thereon. In such embodiments, signal transformation circuitry 124b may be integrated circuitry monolithically integrated with the semiconductor die.

FIG. 9C is a block diagram illustrating components of a target device 930, in accordance with some embodiments of the technology described herein. In the illustrative embodiment of FIG. 9C, target device 930 includes receive antenna 122, signal transformation circuitry 124c, and transmit antenna 126. The output of receive antenna 122 is coupled, via line 933, to an input of signal transformation circuitry 124c. The output of signal transformation circuitry 124c is coupled, via line 946, to transmit antenna 126. Receive antenna 122 may be any suitable type of receive antenna, examples of which are provided herein. Transmit antenna 126 may be any suitable type of transmit antenna, examples of which are provided herein.
