DESCRIPTION
The NE38018 is a low cost gallium arsenide Hetero-Junction
FET housed in a miniature (SOT-343) plastic surface mount
package. The device is fabricated using ion implantation for
improved RF and DC performance, reliability, and uniformity.
Its low noise figure, high gain, small size and weight make it
an ideal low noise medium power amplifier transistor in the 1-
3 GHz frequency range. The NE38018 is suitable for GPS,
PCS, WLAN, MMDS, and other commercial applications.
NEC's stringent quality assurance and test procedures en-
sure the highest reliability and performance.

Note:
1. Typical values of noise figures and associated gain 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.
