An important quantity in the description of any junction circulator is its insertion phase over the frequency response of the specification. This paper provides some experimental data on this quantity for a degree-1 stripline device using an irregular hexagonal resonator for a number of different shape angles. In addition, a phase slope parameter is defined and related to the susceptance slope parameter of the gyrator circuit. The group delay of the junction is also deduced. A relationship between the phase angles of the reflection and transmission scattering parameters is separately deduced and verified.
