Solid-state amplifiers for terahertz electronics

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 our 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 solidstate amplifiers at THz frequencies.
