The main purpose of this paper is to review the framework behind direct digital synthesizer phase-locked loops (DDS-PLLs), as well as to provide a set of novel techniques that can be used during the development and the deployment of phased arrays based on local oscillator (LO) phase shifting approaches. A beam steering transmitter prototype employing our revised DDS-PLL architecture and the experimental results obtained during its characterization are presented. The main contribution of the proposed implementation consists in showing that the output phase increments of the DDS-PLL are unaffected by the frequency multiplication operated by the PLL. The proposed prototype is centered at 3.350 GHz and allows to independently set the phase of its four LOs at 2.453 GHz with an 8-bit resolution. The DDS-PLL architecture is frequency-independent, and the modular structure of its phase control units allows to achieve different phase resolutions with a very small redesign effort.

“…Previously, different approaches were proposed to implement the photonic microwave phase shifter, which can generally be divided into three categories, i.e., slow-light-based method [11]- [15], optical vector-sum technique [16], [17], and optical heterodyne technique [18]- [22]. The slow-light-based photonic microwave phase shifter is implemented through slowing down the optical carrier and/or sidebands in a medium with a tremendous effective refractive index, so the phase of the signal can be continuously tuned by adjusting the time delay introduced by the slow light effect.…”

A polarization-based photonic microwave phase shifter that implemented with an orthogonal circularly-/ linearly-polarized wavelength generator incorporated with a polarizer provides advantages of high scalability, high-speed phase tuning, large operation bandwidth, full-360-degree tunability, flat power response, and compact configuration, making it a key enabler for tunable microwave photonic filtering, optically controlled beamforming, high speed phase coding, large timebandwidth product signal generation, phase noise measurement, and co-site RF signal cancellation. In this paper, the recent advances of polarization-based photonic microwave phase shifters are reviewed. A general model of the polarization-based photonic microwave phase shifter is established, and the applications of the polarization-based photonic microwave phase shifter are described and discussed.

This paper details the design and implementation of a modulator-less beam steering transmitter based on a revised DDS-PLL phase shifter architecture. The proposed topology targets low data rate communications for Internet-of-Things systems, and has been demonstrated using an FPGA evaluation board and a custom PCB with four PLLs centered at 2.453-GHz. Measured system performance for an experimental 32-kbps data rate achieved through a 16-PSK modulation scheme are discussed. The proposed architecture is frequency independent, can be used in multi-band devices and has the potential for being integrated as an RF System-on-Chip.
