Abstract : We present back-to-back GCPW-MS-GCPW (Grounded Coplanar Waveguide-Microstrip lines) transitions on substrates in thin film on cheap silicon wafers, constituted of a 1-cm microstrip line and pads or stubs compatible with CPW probes. Their bandwidth can cover the frequency range between 180 MHz and 60 GHz. These performances are obtained without making via-hole in the substrate and patterning the bottom ground plane. These transitions using the electromagnetic coupling between the bottom and top ground planes simplifies the manufacturing and facilitates the characterization, by means of coplanar probes, of microwave photonic devices realized from materials in thin film and whose driving electrode is a microstrip line, such as electrooptic modulators based on polymer poled by Corona effect
