We report on a multifunctional optoelectronic radio frequency attenuator for millimeter wave applications, designed in a multilayer thin‐film multichip module technology on high resistive silicon. Insertion loss of measurements and electromagnetic simulations of a coplanar waveguide line under illumination demonstrate a contrast of 40 dB at 100 GHz. © 2007 Wiley Periodicals, Inc.
