Abstract

We report our recent investigation of a novel uniplanar transition between microstrip lines and coplanar strips (CPS) which is to be utilized in our velocity-matched distributed photodetector (VMDP). Both FDTD simulations and X-band experiments show broadband, low return loss performance of this newly proposed structure, with a measured 3 dB insertion loss bandwidth of 68 percent for the case of a balanced back-to-back microstrip-to-CPS transition
