The arrangement includes a TEM cavity having a shunt inductive rod having one end connected to one wall of the cavity and a capacitive gap between the other end of the rod and a member of the cavity with the cavity and gap being filled with a solid dielectric material. The thermal coefficient of expansion of the metal of the cavity, the metal of the rod and the dielectric are all selected so that in cooperation with a selected physical dimension of the gap and a selected length of the rod the rate of change of the inductive and capacitive reactance of the cavity are equalized during a temperature variation so that their difference remains zero at the operating frequency of the cavity.
