dc.description.abstractTo achieve a high-data rate wireless communication system with PAM-4 modulationis tested in this project. A MMIC solution is developed and fabricated with TeledyneScientific Instruments, US, in their 250nm InP DHBT-process with f_max=650GHz.The simulated system consists of a RF-DAC, a PA, transmitter and receiver antennawith 40dBi gain, an LNA, a VGA and a PD. ADS simulation shows that the systemlooks promising. The critical part in the system is the RF-DAC based modulator,which is why two different solutions are tested and evaluated.The modulators aredesigned for an LO frequency of 70GHz, though the plan is to double the frequencywhen the function of the chosen RF-DAC is confirmed. The reason to not designfor an LO frequency of 140GHz straight away is to simplify the testing process.Symbol rate for one of the fabricated modulators is tested and confirmed to supporta 40Gbps transmission with a BER of3.7×10−6, and the energy efficiency is betterthan 1.2pJ/bit.
