A repeater device may be utilized to enable forwarding extreme high frequency (EHF) communication between EHF-enabled wireless devices. The repeater device may utilize spatial isolation to prevent and/or reduce interference between received and transmitted EHF RF signals, wherein reception and/or transmission of EHF RF signals in the repeater device may be performed via narrow beams that may enable minimal interference by transmit EHF RF signals to reception of EHF RF. The repeater device may utilize phased arrays to enable performing beamforming, and signal processing operations, including shift and/or amplitude adjustment, may be performed on signals received and/or transmitted via antenna elements in the phased arrays to enable beamforming during reception and transmission of EHF RF signals. Signal processing operations performed in the repeater device may be modifiable to enable continued spatial isolation between receive and transmit EHF RF signal in the repeater device.
