Abstract :
This paper describes the accurate characterization of a photoimageable thick film dielectric with 1 to 110 GHz measurements on a two port microstrip ring resonator. The loss tangent is found to remain below 0.006 up to over 110 GHz. The line losses are found to be better than many reported results for thin film technology, with less than 0.2dB/mm at 80 GHz. Using the data, a 64 GHz bandpass filter and a lumped element 3 GHz low pass filter are designed and measured.
