Two-stage LNA
30 dB gain & 0.8 dB NF at 1575 MHz
Description
ASL30G is a two-stage LNA for GPS receiver low noise
block. 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 system. The amplifier is available in an
SOT-363 package and passes the stringent DC, RF, and
reliability tests.
Package Style: SOT-363
Unconditionally
Stable
Need only 5 components
3 kV Contact Discharge ESD Rating
achievable with one external L (Refer
to an application circuit at page 6)

Note:
1. The number and size of ground via holes in a
circuit board is critical for thermal and RF
grounding considerations.
2. We recommend that the ground via holes be
placed on the bottom of lead pin 2,4 and 5 for
better RF and thermal performance, as
shown in the drawing at the left side.
