BIPOLAR ANALOG INTEGRATED CIRCUITS
µPC2776TB
5 V, SUPER MINIMOLD SILICON MMIC
MEDIUM OUTPUT POWER AMPLIFIER
DESCRIPTION
The µPC2776TB is a silicon monolithic integrated circuits designed as wideband amplifier. This amplifier has
impedance near 50 Ω in HF band, so this IC suits to the system of HF to L band. This IC is packaged in super
minimold package which is smaller than conventional minimold.
The µPC2776TB has compatible pin connections and performance to the µPC2776T of conventional minimold
version. So, in the case of reducing your system size, the µPC2776TB is suitable to replace from the µPC2776T.
These IC is manufactured using NEC’s 20 GHz fT NESAT™ III 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.

Selection point among product line-up
µPC2709TB: Suits to 1 GHz 2.5 GHz operation due to small inductance (e.g. 10 nH) between VCC and output pin.
µPC2776TB: Suits to HF to 2.0 GHz operation due to large inductance (e.g. 100 nH) between VCC and output pin.

DESCRIPTION
1 INPUT
− High-frequency signal input pin. A in-
ternal matching circuit, configured with
6
resistors, enables 50 Ω connection over
a wide band. A multi-feedback circuit is
designed to cancel the deviations of hFE
and resistance.
2 GND

0 Ground pin. Form a ground pattern as
wide as possible to maintain the mini-
mum ground impedance.
4 OUTPUT 4.5 to 5.5 High-frequency signal output pin.
1
Connect an inductor between this pin
and VCC to supply current to the internal
output transistors.
6 VCC
Power supply pin, which biases the in-
ternal input transistor.
Excellent RF characteristics are ob-
tained by a two-stage amplifier circuit.
