Microwave photonics filter

Web4 jan. 2024 · By combining these elements in a single microwave photonics circuit, the team was able to demonstrate programmable filter functions with a record-low noise figure of 15 dB and a radio frequency notch filter with an ultra-high dynamic range of more than 123 dB in 1 Hz bandwidth. WebA new microwave photonic signal processing structure that has the ability to realise frequency and phase shifting operation is presented. The proposed structure uses Serrodyne phase modulation in a dual-polarisation binary phase shift keying (DP-BPSK) dual-drive Mach Zehnder modulator to shift the frequency of an input microwave signal.

WebWe focus on using microwave photonics techniques to demonstrate a widely tunable microwave photonic filter (MPF). This filter allows reconfiguration of filter bandwidth and filter frequency; in addition, it can be tuned to have single or multiple filter bands. Notch filter can also be achieved with photonics techniques. dr phang albany cardiology https://roschi.net
