Abstract :
We present an antenna base station architecture for millimeter-wave radio-on-fiber downlink transmission systems. The architecture is made up of a single InP HPT oscillator, in which InP HPT device simultaneously performs the optically injection-locked oscillation and harmonic optoelectronic mixing. With this, we successfully demonstrate 16QAM radio-on-fiber downlink transmission in 30GHz band.
