1) IIP3 is measured with two tones at an input power of -30 dBm
/tone separated by 1MHz.
Board Layout (FR4, 20x20 mm², 0.8T)
Note: 1) the length of the strip line P1 is given as below at
the PCB with Er = 4.5 and T = 0.8 mm.
P1 Length: 1 mm, Width: 0.3 mm
2) Gain and S11 are in trade-off and varied with the length of P1
