1) OIP3 is measured with two tones at an output power of +10 dBm/tone sepa-
rated by 1 MHz.
Schematic
Note: A shunt RB is a bias resistor requisite to
operate ASL13W properly, while RD as a
voltage drop resistor is added to apply 4.4 V
to the device. A user can easily REDUCE an
operating current by choosing different RB
values with minimized loss only in OIP3 and
P1dB.
