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 C = 1/(2 p fZs).]
