DESCRIPTION
The UPC8178TB is a silicon monolithic integrated circuit
designed as an amplifier for mobile communications. This IC
can realize low current consumption with an external chip
inductorwhichcannotberealizedonaninternal50Ωwideband
matched IC. This low current amplifier operates on 3.0 V. This
deviceismanufacturedusingNEC's30GHzfmaxUHS0(Ultra
HighSpeedProcess)siliconbipolarprocesswhich usesdirect
silicon nitride passivation film and gold electrodes. These
materials can protect the chip surface from pollution and
preventcorrosion/migration.Thus,thisIChasexcellentperfor-
mance, uniformity and reliability.
• HIGH-DENSITY SURFACE MOUNTING:
6-pin super minimold package (2.0 x 1.25 x 0.9 mm)
• LOW WEIGHT:
7 mg (Standard Value)
APPLICATIONS
•
Buffer Amplifiers on 0.1 to 2.4 GHz mobile
communications system
NEC's stringent quality assurance and test procedures ensure
the highest reliability and performance.
ELECTRICAL CHARACTERISTICS
(TA = 25°C, VCC = VOUT = 3.0 V, ZS = ZL = 50 Ω, at LC matched frequency unless otherwise specified))
