Microwave photonic filters with high Q value

This paper firstly presents the fundamental principles of the microwave photonic filters. According to the number of the taps of the microwave signal is finite either infinite, a microwave photonic filter is classified into finite impulse response (FIR) filter and infinite impulse response (IIR) filter. As an example to explain how to implement a microwave photonic filter, a specific FIR configuration is illustrated. Next, the theory and methods around how to gain high Q value is discussed. Then, divided into FIR filter, one-order IIR filter, and multi-order IIR filter, several novel approaches to gain high Q value are discussed and compared. The technical difficulties in multi-order IIR filter are analyzed concretely in this part. In the end, we make a summary for the microwave photonic filters with high Q value.
