This work is focused on the development of a reconfigurable radio-frequency transmitter applied to microwaves and millimeter-waves. Initially, the photonicsbased frequency multiplication technique is presented. Posterior, the proposed device is applied to reconfigurable and convergent optical-wireless networks. The analysis methodology is based on three main steps: numerical simulations; experimental characterization; implementation and test in real optical-wireless networks. Numerical simulations were carried out using the software OptiSystem and the experiments were carried out in the laboratory WOCA (Wireless and Optical Convergent Access) from the National Institute of Telecommunications (Inatel). Numerical and experimental results demonstrate the efficiency of the proposed transmitter and its applications to future telecommunications networks, including 4G and 5G systems.
