Integrated active sensors for near-field scanning of printed circuit boards (PCB) as well as large scale integrated (LSI) circuits have been designed in OMMIC ED02AH GaAs technology. Our frequency target ranges from 1MHz to 3 GHz and is planned to extend up to 10 GHz. Electromagnetic (EM) field simulation results as well as on-wafer measurement results are presented for passive loop and dipole. A wideband amplifier with 22 dB gain and about 10 GHz bandwidth is designed and measurement results are presented. Finally qualitative on-wafer measurement results for the active sensors are presented.
