A reconfigurable photonic microwave mixer is proposed using a 90° optical hybrid. To
perform the reconfigurable mixing, an optical carrier is split into two branches. One portion is …

Image-reject mixers (IRMs) play an important role in microwave and millimeter-wave
receivers to eliminate the interference from the image frequency. The keys to realizing a …

A microwave photonic mixer for up-and down-conversion based on dual parallel in-phase
and quadrature (I/Q) modulators is proposed. Dual parallel I/Q modulators and 90-degree …

The emerging new concepts and technologies based on microwave photonics have led to
an ever increasing interest in develo** innovative radar systems with a net gain in …

An all-optical microwave photonic frequency downconverter with tunable full range
continuous phase shift is presented. In the proposed system, the radio frequency (RF) and …

A novel wideband microwave frequency divider based on a single-loop optoelectronic
oscillator (OEO) is proposed and demonstrated. The Mach-Zehnder modulator in the OEO is …

An ultra-wideband microwave photonic frequency downconverter is proposed based on
carrier-suppressed single-sideband (CS-SSB) modulation. A radio frequency (RF) signal …

The conversion gain of a photonic microwave mixer is often limited by the large carrier of the
modulated optical signal, and may be further deteriorated by the chromatic dispersion …

A microwave photonic mixer based on a frequency-doubled local oscillator (LO) is
proposed. The carrier-suppressed single-sideband (CS-SSB) modulation of the–first-order …
