Abstract :
Experimental results are presented for several microstrip dielectric filters which use temperature compensated resonators. The various contributions to the insertion loss are quantified, showing that resonator-resonator coupling losses are about a factor of two times the microstrip-resonator coupling losses. Balanced and unbalanced couplings have been investigated and the effect of temperature is also presented.
