ABSTRACT:
A TE.sub.101 mode cavity resonator housing 60 has a truss 70 securely mounted to one of its broadwalls 72. The truss 70 is fabricated from a material having a lesser coefficient of expansion than that of the material from which the housing 60 is fabricated. The difference between the coefficients of expansion results in a difference in expansion and contraction of the materials over temperature. The thermal expansions and contractions in the housing 60 material result in variations in the natural resonant frequency of the housing 60. These variations in natural resonant frequency are compensated by offsetting thermal expansions and contractions in the truss 70 material.
