TEST CIRCUIT
EXAMPLE OF APPLICATION CIRCUIT
The application circuits and their parameters are for references only and are not intended for use in actual design-ins.
CAPACITORS FOR THE V
the input and output pins.
can be supplied against V
impedance. Their capacitance are therefore selected as lower impedance against a 50 Ω load. The capacitors thus
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, fc = 1/(2πRC).
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
