A method for de-embedding the coaxial to waveguide transition is proposed and analyzed experi-mentally. The method involves the determination of a model for this type of transition which consists of a lossy two-port and two lossless transmission lines. The parameters of the transmission lines can be computed based on simple formulas, while the ABCD matrix of the two-port can be obtained by solving a matrix equation using a commercial software. Two measurements of scattering parameters are performed to develop the proposed model, for thru and short-circuit calibration standards. The phase constant and return-loss for a waveguide section inserted between two coaxial to waveguide transitions are obtained by de-embedding the transitions using the proposed model. The results are in very good agreement with the expected ones. All results are obtained in the frequency band ranging from 8 to 12 $\boldsymbol{GHz}$.
