AST54S

High Gain, Low Noise Amplifier

1) OIP3 is measured with two tones at an output power of +4 dBm/tone separated by 1MHz.

1) 100% in-house DC & RF testing is done on packaged products before taping

* Please find the max. input power data from http://www.asb.co.kr/pdf/Maximum_Input_Power_Analysis.pdf

The max. input power, in principle, depends upon the application frequency and the matching circuit.
