TEST CIRCUIT
INDUCTOR FOR THE OUTPUT PIN
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 (Refer to the following page).
CAPACITORS FOR THE V

can be supplied against V
impedance. Their capacitances are therefore selected as lower impedance against a 50 Ω load. The capacitors thus
perform as high pass filters, suppressing low frequencies to DC.
