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

Other packaging and interconnect techniques may be utilized as well, including ceramic or plastic covers, laminate (PCB) technologies, or any other suitable packaging or interconnect solutions that suitably protect the device from the environment and/or physical damage and that allow for suitable first level connections between the semiconductor die and the antenna and package (e.g., substrate 700) and allow for suitable second level connections between the packaged device and the next level of interconnection (e.g., the system level board of a product into which the micro-localization components are integrated such as, for example, product 200).

FIG. 8A is a block diagram illustrating components of an interrogator device 800, in accordance with some embodiments of the technology described herein. In the illustrative embodiment of FIG. 8A, interrogator device 800 includes waveform generator 110, transmit and receive circuitry 112a, transmit antenna 114, receive antenna 116, and control circuitry 118. Transmit and receive circuitry 112a includes frequency multipliers 802, 804, 806, and 809, amplifiers 803, 805, 807, 808, 810, 811, 813, and 814, frequency mixer 812, filter 815, and analog-to-digital converter (ADC) 816. Each of the above-identified components of transmit and receive circuitry 112a may be of any suitable type, as aspects of the technology described herein are not limited in this respect.
