Operation of dielectric nonlinear transmission lines based on ceramic PZT slabs

De-poled PZTs (Lead-Zirconium-Titanate) were studied in the terms of nonlinearity properties, dielectric losses and breakdown. As shown in this paper de-poled PZTs have lower permittivity and dielectric losses compared to poled ones and BT (Barium Titanate) ceramic dielectrics. This was confirmed by measuring the permittivity, polarization curve and, tangent loss (δ) of this material. As discussed herein lower dielectric losses and permittivity may favor the replacement of BT tiles by PZTs in dielectric nonlinear transmission lines used for RF generation.
