Abstract
We have shown a modified version of the binary white cell-based true time delay (TTD) generator architecture to allow the use of a deformable mirror device (DMD). If 10 bits of delay are required, then each beam will make 20 bounces and use 20 pixels on the DMD. A commercial DMD with 500,000 elements can thus in principle provide 10 bits of delay for 50,000 antenna elements
