1. An interrogator device, comprising:
a substrate;
a semiconductor die mounted on the substrate;
a transmit antenna on the substrate and shaped to convert a first electric signal to a first radio-frequency (RF) signal for transmission to a target device, the first RF signal having a first center frequency between 50 GHz and 70 GHz;
a receive antenna on the substrate and shaped to convert a second RF signal transmitted from the target device to a second electric signal, the second RF signal having a second center frequency between 100 GHz and 140 GHz; and
circuitry integrated with the semiconductor die and configured to:
provide the first electric signal to the transmit antenna and to receive the second electric signal from the receive antenna, and
generate a third electric signal indicative of a distance between the interrogator device and the target device based on the first and second electric signals.
