    • Extremely High Frequency (EHF) distributed antenna systems and related components and methods are disclosed. In one embodiment, a base unit for distributing EHF modulated data signals to a RAU(s) is provided. The base unit includes a downlink data source input configured to receive downlink electrical data signal(s) from a data source. The base unit also includes an E-O converter configured to convert downlink electrical data signal(s) into downlink optical data signal(s). The base unit also includes an oscillator configured to generate an electrical carrier signal at a center frequency in the EHF band. The base unit also includes a modulator configured to combine the downlink optical data signal(s) with the electrical carrier signal to form downlink modulated optical signal(s) comprising a downlink optical data signal(s) modulated at the center frequency of the electrical carrier signal. The modulator is further configured to send the downlink modulated optical signal to the RAU(s).
