Abstract

Fabrication of printed inductors on alumina substrate using circular and rectangular shapes of multiturn inductors were studied. The values of the inductors were found to be close to the design values. Inductors with 6 mil spacing were found to be closer to the design values than the 4 and 5 mil of spiral inductors. It may be because of the mutual inductor effect between the turns. Q values of the smaller inductor are comparable to the discrete values. Low-pass filters built using printed inductors between 100 and 400 MHz cut-off frequencies provided close to the simulated performances in which discrete component model were used
