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 an SOT-363 package and passes the

stringent DC, RF, and reliability tests.
