Abstract :
The generation and detection of EHF microwave signals through the photomixing of two independent CW laser sources at commercial gallium-arsenide antennas is presented as a versatile technique for short range EHF communications. More than to eliminate further amplification before the irradiating antenna, the proposed technique is able to generate MMW signals at the EHF range with a maximum strength difference of 10 dB through the full range.
