This paper presents the transmission of broad-band complex modulated signals with data rates up to 64 Gbit/s using an analog front-end based on monolithic microwave integrated circuits (MMICs) at a carrier frequency of 300 GHz. Besides the typical modulation formats like BPSK, QPSK, and 16QAM a non-common modulation format 8APSK is introduced and measured. The maximal transmitted symbol rate is 32 Gbd. The signal quality is evaluated in terms of error vector magnitude, which shows values of -10.8 dB for BPSK and -10.10 dB for QPSK at a symbol rate of 32 Gbd and values of -14.8 dB for 16QAM at a symbol rate of 2 Gbd.
