3 V, SUPER MINIMOLD SILICON MMIC
WIDEBAND AMPLIFIER FOR MOBILE COMMUNICATIONS
BIPOLAR ANALOG INTEGRATED CIRCUIT
DESCRIPTION
The
PC2745TB and
PC2746TB are silicon monolithic integrated circuits designed as buffer amplifier for mobile
communications. These low current amplifiers operate on 3.0 V (1.8 V MIN.).
These ICs are manufactured using our 20 GHz f
T
NESATIII 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, these IC have excellent performance, uniformity and reliability.

Signal input pin. A internal matching
circuit, configured with resistors, enables
50
connection over a wide band. this
pin must be coupled to signal source with
capacitor for DC cut.

GND
0
Ground pin. This pin should be connected
to 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 wide ground pattern to
decrease impedance difference.

OUTPUT
1.95
Signal output pin. A internal matching
circuit, configured with resistors, enables
50
connection over a wide band. This
pin must be coupled to next stage with
capacitor for DC cut.
