Customizable printed inductors on LTCC substrates for RF applications

This work is aimed to demonstrate the potential of Inkjet printing combined with electroless growth to implement high performance RF inductors on standard low temperature co-fired ceramic substrates. Enhanced customization and tuning are the main advantage of this technological combination in front of standard low temperature co-fired ceramic technology. Two sets of samples have been fabricated and their equivalent inductance and quality factors as a function of frequency are compared. The obtained results are discussed and correlated with the technological parameters of the fabrication process.
