We experimentally demonstrate a heterodyne communication link using a p-i-n photodiode and a photoconductor coupled to THz antennas without bandwidth-limiting electronic components. As a proof-of-concept, a 100 Mbit/s BPSK stream is successfully transmitted at three different channels, spaced by 40 GHz, down-converting the wireless carrier to an intermediate frequency of 3.7 GHz. Optical frequency combs are employed for sub-THz generation and down-mixing to reduce the phase noise of the system.
