Minimisation of phased error in digitally controlled attenuator
Abstract
A method for minimizing phase errors in null steering by amplitude-only control is discussed. The basic design principle of attenuators is summarized. It is shown that very small phase errors over the whole attenuation range can be obtained if more diodes are used.
