    Abstract: Systems, methods, devices and apparatuses directed to transceiver devices are disclosed. In accordance with one method, a first set of antenna positions in a first section of a set of sections of a circuit layout for the circuit package is selected. The method further includes selecting another set of antenna positions in another section of the circuit layout such that an arrangement of selected antenna positions of the other set is different from an arrangement of selected antenna positions of a previously selected set of antenna positions. The selecting another set of positions in another section is iterated until selections have been made for a total number of antennas. The selecting the other set is performed such that consecutive unselected positions in the other section do not exceed a predetermined number of positions. In addition, antenna elements are formed at the selected positions to fabricate the circuit package.

    Abstract: Frequency multipliers include a pair of transistors each connected to a common impedance through a respective collector impedance formed from a transmission line. Each transmission line has a length between about one quarter and about one eighth of a wavelength of an input signal frequency and is tuned to produce a large impedance at a collector of the respective transistor at the input signal frequency. The output frequency between the collector impedances and the common impedance is an even integer multiple of the input frequency.

    Abstract: A first 1:N frequency divider has an input configured to be coupled to one of two signals and a second 1:N frequency divider has an input configured to be coupled to another of the two signals. A mixer includes two inputs, where each input is coupled to an output of one of the first and second 1:N frequency dividers. A low-pass filter has an input coupled to an output of the mixer and an analog-to-digital converter (ADC) has an input coupled to an output of the low-pass filter. A data collection and analysis block repeatedly changes a phase of an output of the first 1:N divider, collects a set of digitized data generated by the ADC, and estimates the phase difference between the two signals based on the set of digitized data.

    Abstract: A radar-based security screening system for detecting objects is described. The screening system includes a radar transmitter, a radar receiver, and a processing unit. In use, the radar transmitter steers a radar beam across a screening volume. The radar receiver, in turn, receives a return signal from an object over time as the object moves in the screening volume to create a three-dimensional temporal signature for the object. The processing unit classifies the three-dimensional temporal signature utilizing a classification process based on a deep neural network model, and provides an alert when the object is classified as an object of interest. During screening, a screened person is not required to remain still in a confined volume and is not exposed to harmful radiation.
