The TriQuint 1034474 (alternate marking 854909) is a gallium arsenide (GaAs) pseudomorphic high electron mobility transistor (pHEMT) discrete device, as indicated by its manufacturer and common application of TriQuint (now Qorvo) GaAs devices. The “D/C 0720” marking denotes a date code of week 07 of the year 2020. This date code is critical for traceability and shelf life considerations. The “ROHS” designation confirms compliance with the Restriction of Hazardous Substances directive, indicating the device is lead-free and adheres to environmental regulations. Performance characteristics, such as gain, noise figure, and power output, are contingent on specific biasing and matching network configurations, necessitating reference to the original equipment manufacturer’s (OEM) application notes or a comprehensive datasheet for precise operational parameters. Its intended use is likely in high-frequency amplifier applications within communication systems.
