Abstract :
We present new experimental data of the first multi-band adaptive feedforward linearized RF photonic link. Adaptive feedforward third order correction of 18-24 dB and SFDR values >110 dB-Hz2/3 over a multi-band operating bandwidth (S through Ku) with instantaneous bandwidths approaching 1 GHz, are demonstrated. Similar linearity performance is also demonstrated under pulsed operation of the wideband adaptive linearized RF photonic link.
