ASL19W

DC-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.

Board Layout (FR4, 40x40 mm

S-parameters & K-factor

APPLICATION CIRCUIT

voltage drop resistor is added to apply 4.4 V

to the device. A user can easily REDUCE an

values with minimized loss only in OIP3 and

P1dB.
