  Microwave photonics (MWP) has adopted a number of important concepts and
technologies over the recent pasts, including photonic integration, versatile
programmability, and techniques for enhancing key radio frequency performance
metrics such as the noise figure and the dynamic range. However, to date, these
aspects have not been achieved simultaneously in a single circuit. Here, we
demonstrate, for the first time, a multi-functional integrated microwave
photonic circuit that enables on-chip programmable filtering functions while
achieving record-high key radio frequency metrics of >120 dB.Hz dynamic range
and 15 dB of noise figure that are previously unreachable. We unlock this
unique feature by versatile complex spectrum tailoring using an all integrated
modulation transformer and a double injection ring resonator as a
multi-function optical filtering component. This work breaks the conventional
and fragmented approach of integration, functionality and performance that
currently prevents the adoption of integrated MWP systems in real applications.
