LNA FOR GPS APPLICATIONS
DESCRIPTION
High gain and low noise figures make the SMA428A an
ideal solution for Low Noise Amplifiers and receiver
front end stages up to 2.5 GHz. SMA428A’s typical
supply voltage range is 2.4 to 3.3 volts. It shows
excellent performances in terms of NF, Gain and
current consumption, using just 3 external matching
components. Applying supply voltage to the GS pin and
grounding Vcc pin, it provides a reduced gain step of 35
dB. SMA428A is housed in ultra miniature SOT323-6L
package(LEAD FREE), the relative dimensions are
1.15mmx1.8mm with 0.8mm thickness.
