The application circuits and their parameters are for reference only and are not intended for use in actual design-ins.
Capacitors for V
CC
, input and output pins
1 000 pF capacitors are recommendable as bypass capacitor for V
CC
pin and coupling capacitors for input/output
pins.
Bypass capacitor for V
CC
pin is intended to minimize V
CC
pin’s ground impedance. Therefore, stable bias can be
supplied against V
CC
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
π
fZs).]
