SILICON RFIC
LOW CURRENT AMPLIFIER
FOR MOBILE COMMUNICATIONS
UPC8178TB
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
inductor which cannot be realized on an internal 50 Ω wideband
matched IC. This low current amplifier operates on 3.0 V. This
device is manufactured using NEC's 30 GHz fmax UHS0 (Ultra
High Speed Process) silicon bipolar process which uses direct
silicon nitride passivation film and gold electrodes. These
materials can protect the chip surface from pollution and
prevent corrosion/migration. Thus, this IC has excellent perfor-
mance, uniformity and reliability.
NEC's stringent quality assurance and test procedures ensure
the highest reliability and performance.

PIN FUNCTIONS (Pin Voltage is measured at VCC = 3.0 V)
Ground pin. This pin should be connected to the
system ground with minimum inductance. Ground
pattern on the board should be formed as wide
as possible. All the ground pins must be
connected together with a wide ground pattern to
decrease impedance difference.
Signal input pin. An internal matching circuit,
configured with resistors, enables a 50 Ω
connection over a wide band. This pin must be
coupled to the signal source with the capacitor for
DC out.
Signal output pin. This pin is designed as the
collector output. Due to the high impedance
output, this pin should be externally equipped
with LC matching circuit to next stage. For L, a
size 1005 chip inductor can be used.
Power supply pin. This pin should be externally
equipped with a bypass capacitor to minimize it's
impedance.
