Stripline devices

Measurement of device bandwidths in the order of 100 GHz typically requires heterodyne detection and a stripline electrode configuration such as that illustrated in Fig. 31. The response of polymeric electro-optic modulators is typically flat to 100 GHz. Fall off above that frequency (Fig. 32) can be traced to resistive losses in millimeter wave transmission structures and in the metal electrodes. 

The most frequently used ferrite device is a three-port circulator in waveguide or stripline configuration, as illustrated in Fig. 9.54. In the waveguide configuration a ferrite cylindrical disc is located symmetrically with respect to the three ports. In the stripline configuration two ferrite discs are placed on each side of the strips. In both cases a magnetic field is applied perpendicular to the planes of the discs.
