We present a stabilized microwave-frequency transfer technique that is based on optical phase sensing and optical phase actuation. This technique shares several attributes with optical-frequency transfer and, therefore, exhibits several advantages over other microwave-frequency transfer techniques. We demonstrated the stabilized transfer of an 8000 MHz microwave-frequency signal over a 166 km metropolitan optical fiber network, achieving a fractional frequency stability of 6.8×10-14  Hz/Hz at 1…

Stable radio frequency transfer over fiber based on microwave photonic phase shifter.
A radio frequency (RF) phase-stable transmission over fiber based on microwave photonic phase shifter is demonstrated and the phase perturbation caused by fiber-length variations can be compensated automatically via controlling the direct-current bias voltage of the DMZM.

The MeerKAT is a precursor for the ldquosmall dish plus single-pixel wide-band feedrdquo scenario for the Square Kilometre Array (SKA), and the individual receptors match the SKA draft specification for midband dishes.
A new language, Opt, is proposed for writing these objective functions over image- or graph-structured unknowns concisely and at a high level and automatically transforms these specifications into state-of-the-art GPU solvers based on Gauss-Newton or Levenberg-Marquardt methods.
