Abstract :
This paper presents near electric field measurements above a directional coupler at 10 GHz and a Texas Instruments 2-20 GHz TGA8310-SCC distributed low noise amplifier at 14.5 GHz. The measurements are performed with a low cost modulated scattering system using 100 /spl mu/m long monopole probes with monolithically integrated Schottky diodes on a 40 /spl mu/m thick high resistivity silicon substrate. Normal electric field intensity and phase maps are presented and demonstrates the possibility of using this mapping technique for low cost MMIC diagnostics.
