60 GHz Resonant Photoreceiver with an Integrated SiGe HBT Amplifier for Analog Radio-over-Fiber Links

A photoreceiver is presented for remote antennas in the unlicensed 60 GHz band utilizing an amplifier designed to present a matched impedance to a photodiode. The photoreceiver offers 29 dB higher gain than a reference photodiode over a 3 dB bandwidth of 5.7 GHz while consuming 33.6 mW. It is demonstrated up to 20 Gbps over 5 km SSMF at 4 Gbaud using QAM32 with an RMS EVM of 11.5%.
