DESCRIPTION
The
PC2747TB,
PC2748TB are silicon monolithic integrated circuits designed as amplifier for mobile
communications. These ICs are packaged in super minimold package which is smaller than conventional minimold.
These ICs are manufactured using our 20 GHz fT NESAT 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, these ICs have excellent performance, uniformity and reliability.

TEST CIRCUIT
EXAMPLE OF APPLICATION CIRCUIT
The application circuits and their parameters are for reference only and are not intended for use in actual design-ins.
CAPACITORS FOR 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 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 fC = 1/(2 RC).]

NOTES ON CORRECT USE
(1) Observe precautions for handling because of electro-static sensitive devices.
(2) Form a ground pattern as widely as possible to minimize ground impedance (to prevent undesired
oscillation).
All the ground pins must be connected together with wide ground pattern to decrease impedance difference.
(3) The bypass capacitor should be attached to VCC line.
(4) The DC cut capacitor must be attached to input and output pin.
