3) Measurement condition

A) Oscilloscope

•Bandwidth should be 5 times higher than DUT’s output frequency (4 GHz).

•Probe ground should be placed closely from test point and lead length should be as short as possible.

B) By-pass capacitor 1 (approx. 0.01 μF to 0.1 μF) places closely between Vcc and GND.

C) By-pass capacitor 2 (approx. 10 μF) places closely between power supply terminals on the board.

D) Use the current meter whose internal impedance value is small.

E) Power supply

• Start up time (0 Vg90 %Vcc) of power source should be more than 150 μs and

slew rate should be less than 19.8 mV/μs.

• Impedance of power supply should be as low as possible.
