Abstract :
This paper reports on the demonstration of a voltage switchable barium strontium titanate solidly mounted resonator filter at 6 GHz. The filter insertion loss was measured to be -4.26 dB and the return loss to be -13.5 dB. The 3 dB bandwidth was measured to be 72 MHz and the quality factor was calculated to be 83. The data was collected at a dc bias voltage of 10 V.
