ASL19W

5-3000 MHz High Linearity LNA MMIC

1) OIP3 is measured with two tones at an output power of +10 dBm/tone

separated by 1 MHz.

Current (mA)

Note: A shunt RB is a bias resistor requisite to

operate ASL19W 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.
