the input and output pins.

The coupling capacitors, connected to the input and output pins, are used to cut the DC and minimize RF serial

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.

To obtain a flat gain from 100 MHz upwards, 1 000 pF capacitors are used in the test circuit. In the case of under

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

πRfc).
