BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC1678G
5 V-BIAS, +17.5 dBm OUTPUT, 2.0 GHz WIDEBAND
Si MMIC AMPLIFIER
DESCRIPTION
The µPC1678G is a silicon monolithic integrated circuit designed as medium output power amplifier for high
frequency system applications. Due to +17.5 dBm TYP. output at 2 GHz, this IC is recommendable for transmitter
stage amplifier of L BAND wireless communication systems. This IC is packaged in 8-pin plastic SOP.
This IC is manufactured using NEC’s 20 GHz fT NESAT™IV silicon bipolar process. This process uses silicon
nitride passivation film and gold electrodes. These materials can protect chip surface from external pollution and
prevent corrosion/migration. Thus, this IC has excellent performance, uniformity and reliability.
FEATURES
• Supply voltage
• Saturated output power
• Wideband response
• Power gain
• Isolation
: VCC = 4.5 to 5.5 V
: PO(sat) = +17.5 dBm TYP. @ f = 500 MHz with external inductor
: fu = 2.0 GHz TYP. @ 3 dB bandwidth
: GP = 23 dB TYP. @ f = 500 MHz
: ISL = 35 dB TYP. @ f = 500 MHz
APPLICATIONS
• PA driver for high frequency system.

50 Ω connection over a wide band.
A multi-negative feedback circuit is
designed to cancel the deviations of hFE
and resistance.
This pin must be coupled to signal source
with capacitor for DC cut.
0 Ground pin. This pin should be
connected to system ground with
minimum inductance. Ground pattern on
the board should be formed as widely as
possible. All the ground pins must be

connected together with wide ground
pattern to decrease impedance
difference.
