Abstract :
A 120-GHz-band 10-Gb/s wireless link using an InP-HEMT-based MMIC was introduced. This link is suitable for last-mile access of 10GbE, live-relay transmission for 4K cinema, and multiplexed HD videos. The transmitter and receiver MMICs were developed to extend the link distance while maintaining the capacity of 10 Gb/s. The 120-GHz wireless link using the MMICs successfully demonstrated wireless transmission of 10GbE over the link distance of over 5 km. We also designed QPSK modulator and demodulator MMICs to improve the spectral efficiency of the wireless link. Fabricated QPSK MMICs and modules performed 10-Gb/s transmission with the BER of 10-10 at the received power of -38.5 dBm. In the future, we hope to implement QPSK modules in the 120-GHz-band wireless link equipment. We would also like to advance the QPSK modulator and demodulator MMICs and modules to handle bit rates of up to 20 Gb/s.
