BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC2749TB
3 V, SUPER MINIMOLD SILICON MMIC
WIDEBAND AMPLIFIER
FOR MOBILE COMMUNICATIONS
DESCRIPTION
The µPC2749TB is a silicon monolithic integrated circuit designed as amplifier for mobile communications. This
IC is packaged in super minimold package which is smaller than conventional minimold.
The µPC2749TB has compatible pin connections and performance to µPC2749T of conventional minimold
version. So, in the case of reducing your system size, µPC2749TB is suitable to replace from µPC2749T.
This IC is manufactured using NEC’s 20 GHz fT NESATTM lll 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
• High-density surface mounting
• Supply voltage
• Noise figure
• Upper limit operating frequency
: 6-pin super minimold package
: VCC = 2.7 to 3.3 V
: NF = 4.0 dB TYP. @ f = 1.9 GHz
: fu = 2.9 GHz TYP. @ 3 dB down below from gain at f = 0.9 GHz
APPLICATION
• GPS receiver
• Wireless LAN

CAPACITORS FOR THE VCC, INPUT AND OUTPUT PINS
1 000 pF capacitors are recommendable as bypass capacitor for VCC pin and coupling capacitors for input/output
pins.
Bypass capacitor for VCC pin is intended to minimize VCC pin’s ground impedance. Therefore, stable bias can be
supplied against VCC fluctuation.
Coupling capacitors for input/output pins are intended to minimize RF serial impedance and cut DC.
To get a flat gain from 100 MHz up, 1 000 pF capacitors are assembled on the test circuit. [Actually, 1 000 pF
capacitors give flat gain at least 10 MHz. In the case of under 10 MHz operation, increase the value of coupling
capacitor such as 2 200 pF. Because the coupling capacitors are determined by the equation of C = 1/(2 πfZs).]
