From: Jan Panteltje on 28 May 2010 14:10 Abstract -- With the fMAX of current generation InP transistors pushing above 1-THz and new transistor scaling in progress, the operational frequency of solid-state amplifiers is being pushed towards THz frequencies. In this paper we present out latest work towards demonstrating THz frequency amplifiers, including measured gain and noise performance of a 0.48 THz low noise amplifier using scaled InP transistors. Initial performance of next generation transistors is also presented, along with infrastructure necessary to package and operate solid- state amplifiers at THz frequencies. http://www.as.northropgrumman.com/products/mps_mimic/assets/SState_Amp_Terahertz_Elec.pdf
