Broadband SDLVA, SGA, SDGVGA, and vector modulator elements for Intelligent RF Microsystems

Design and performance of state of the art wideband MMICs for Intelligent RF Microsystems are described. These include a SDLVA with the widest reported bandwidth of 5 to 20 GHz, an SGA with DC to greater than 20 GHz frequency response, a four bit 5 to 16 GHz SDGVGA and a 256 state vector modulator covering 6 to 16 GHz.
