Integrated Microstrip and Antipodal Fin-Line Leads to Enhanced Performance P.I.N. Diode Components

Distributed microstrip line tuning elements are used in conjunction with fin-line techniques to design p.i.n. diode switches for the 26 - 110 GHz frequency band. Experimental results are presented for components utilising the forward and reverse switching modes operating at centre frequencies of 34 GHz and 94 GHz.
