Abstract

We present the enhancement of the link performance of the railio-over-fiber system at 60 GHz. by using the system-on-packagc (SoP) electroabsorption modulator (EAM) module with two-stage low-noise amplifiers (LNAs). When compared with the performance of the link that used the narrow-band EAM module without any pro-amplifier, the RF gain of the link that used the SoP module was increased by 30 dB and the noise figure was reduced by 30 dB with a little sacrifice in dynamic range at an EAM bias point that gave the maximum modulator slope efficiency.
