1 / 4 page FEATURES • VERY LOW NOISE FIGURE: 0.40 dB Typical at 12 GHz • HIGH ASSOCIATED GAIN: 12.5 dB Typical at 12 GHz •LG ≤ 0.20 µm, WG = 200 µm • LOW COST METAL CERAMIC PACKAGE • TAPE & REEL PACKAGING OPTION AVAILABLE ULTRA LOW NOISE PSEUDOMORPHIC HJ FET NE32984D DESCRIPTION The NE32984D is a pseudomorphic Hetero-Junction FET that uses the junction between Si-doped AlGaAs and undoped InGaAs to create very high mobility electrons. The device features mushroom shaped TiAl gates for decreased gate resistance and improved power handling capabilities. The mushroom gate also results in lower noise figure and high associated gain. This device is housed in an epoxy-sealed, metal/ceramic package and is intended for high volume con- sumer and industrial applications. NEC's stringent quality assurance and test procedures assure the highest reliability and performance.

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 tuned for the "generic" type but not each specimen.
