Description
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.
