Abstract
Three procedures (method of Ou, Paolino and Kajfez) for the design of CPW Lange couplers are compared for the first time. For each method, the couplers geometry is determined using a quasi-TEM program and verified by full electromagnetic simulations. The couplers are finally fabricated in a multilayer thin-film MCM-D process. The method of Paolino gives the best results. In the 10.8-14.9 GHz band, we have obtained a return loss below ¿18 dB, isolation below ¿20 dB, an amplitude balance below 0.2 dB and a phase balance of (90.7+/¿0.9) deg. An excellent correspondence between measurement and simulations has been obtained.
