AST163

High Gain, Low Noise Amplifier

1) OIP3 is measured with two tones at an output power of -5dBm/tone separated by 1MHz.

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.

 1.1 dB NF at 1575 MHz

 One-stage LNA

AST163 is a one-stage LNA for GPS, DMB, and

satellite receiver low noise blocks. It has a low noise,

high gain, and high linearity over a wide range of

frequency up to 6 GHz. It is also suitable for use in

the low noise amplifier block of the mobile wireless

systems of T-DMB, CDMA, GSM, PCS, WCDMA,

WiBro, WiMAX, and WLAN so on. The amplifier is

available in a SOT363 package and passes the

stringent DC, RF, and reliability tests.
