An InGaAs/InAlAs/InP HEMT with sub-50nm EBL gate has been developed for sub-millimeter wave (SMMW) power amplifier (PA) applications. In this paper, we report the device performance including high drain current, high gain, high breakdown voltage and scalability to large gate periphery, which are essential for achieving high output power at these frequencies. Excellent yield, process uniformity and...
In this letter, we describe the design, fabrication, simulation, and measured performance of a single-stage and three-stage 320 GHz amplifier using Northrop Grumman Corporation's (NGC) 35-nm InP high electron mobility transistor submillimeter-wave monolithic integrated circuit (S-MMIC) process. On-wafer S-parameter measurements using an extended waveguide band WR3 vector network analyzer system were...
