Its low noise figure makes this device appropriate for use in the second or third stages of low noise amplifiers operating in the 1 - 14 GHz frequency range. The device is fabricated using ion implantation for improved RF and DC performance, reliability, and uniformity. These devices feature a recessed 0.3 micron gate and triple epitaxial technology. NEC's stringent quality assurance and test procedures ensure the highest reliability and performance.

Typical values of noise figures are those obtained when 50% of the devices from a large number of lots were individually measured in a circuit with the input individually tuned to obtain the minimum value. Maximum values are criteria established on the production line as a "go-no-go" screening test with the fixture tuned for the "generic" type but not for each specimen.
