ELECTRICAL CHARACTERISTICS
TEST CIRCUIT
INDUCTOR FOR THE OUTPUT PIN
an inductor between the V
voltage drop to output enable high level. In terms of AC, the inductor makes output-port impedance higher to get
enough gain. In this case, large inductance and Q is suitable.

impedance. Their capacitances are therefore selected as lower impedance against a 50
perform as high pass filters, suppressing low frequencies to DC.
10 MHz operation, increase the value of coupling capacitor such as 10 000 pF. Because the coupling capacitors are
determined by equation, C = 1/(2 Rfc).

The inductor has both DC and AC effects. In terms of DC, the inductor biases the output transistor with minimum
Capacitors of 1 000 pF are recommendable as the bypass capacitor for the V
The bypass capacitor connected to the V
The coupling capacitors, connected to the input and output pins, are used to cut the DC and minimize RF serial
To obtain a flat gain from 100 MHz upwards, 1 000 pF capacitors are used in the test circuit. In the case of under
