ASL19C

5 ~ 3000 MHz High Linearity LNA MMIC

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

rated by 1 MHz.

Note: A shunt RB is a bias resistor requisite to

operate ASL19C properly, while RD as a volt-

age drop resistor is added to apply 3.9 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.
