Experimental measurements of coplanar waveguide (CPW) circuits atop thin films of ferroelectric Ba(x)Sr(1-x)TiO3 (BST) were made as a function bias from 0 to 200 V and frequency from 0.045 to 20 GHz. The resulting phase shifts are compared with metho
The design, simulation and characterization of a novel Ka-band (32.05 plusmn 0.25 GHz) rectangular waveguide branch-line hybrid unequal power combiner is presented. The manufactured combiner was designed to combine input signals, which are in phase a

In this paper, there is much interest in using vacuum electronics in the terahertz regime because of their superior power and efficiency capabilities compared to solid state power amplifiers (SSPA's) at high frequencies. However power and efficiency
