Proposal for 60 GHz wireless transceiver for the radio over fiber system

• A 60 GHz mm-wave wireless transceiver is proposed for radio over fiber (RoF) system.
• The novel transceiver scheme can offer an effective solution to overcome LO leakage and I/Q mismatch.
• The system co-simulation has shown the feasibility and effectiveness of this scheme.
• The obtained results of the designed wireless transceiver could meet the requirements in the RoF system.

A 60 GHz mm-wave wireless transceiver for radio over fiber (RoF) is proposed, using sub-harmonic mixer and IF digital signal processing. This scheme can overcome LO leakage and I/Q mismatch. Moreover, an effective verification method of co-simulation between VPI and ADS platforms is considered, this gives full play to the respective advantages of them and in this way we can obtain the results. From these results of the designed wireless transceiver measured by frequency and time domain, we find that 1 Gbit/s data signals carried by 60 GHz mm-wave signals can be successfully recovered. Additionally, the isolation and the conversion loss of the mixer are more than 20 dB, less than 17 dB, respectively. Moreover, the output power of the 60 GHz transceiver is nearly linear with different input powers that are more than −30 dB m.
