We present a wavelength-dependent optical true time delay (TTD) for K-band radio beamformer targeting home-satellite communication. A proof-of-concept of optically-assisted radio beamformer with a TTD bandwidth of 2GHz is experimentally demonstrated. The beamformer is capable of generating multiple radio beams if multiple wavelengths are employed
