Abstract

We present experimental results of 10-Gb/s W-band wireless transmission using a four element linear array. The 10-Gb/s transmission is shown when photonically steered to 0° and ± 35° from antenna boresight. In this letter, photonic techniques are used for signal generation, distribution, and time delay. Photonic true-time delay is shown to allow for steering of broadband millimeter-wave signals with no noticeable beam squint across frequency. High power, high frequency photodiodes are used for optical-to-electrical conversion to directly radiate from the array without power amplifiers.
