ATF-35143
Low Noise Pseudomorphic HEMT
in a Surface Mount Plastic Package
Data Sheet
Description
Avago’s ATF-35143 is a high dynamic range, low noise,
PHEMT housed in a 4-lead SC-70 (SOT-343) surface
mount plastic package.
Based on its featured performance, ATF-35143 is suitable
for applications in cellular and PCS base stations, LEO
systems, MMDS, and other systems requiring super low
noise figure with good intercept in the 450 MHz to 10
GHz frequency range.
Other PHEMT devices in this family are the ATF-34143
and the ATF-33143. The typical specifications for these
devices at 2 GHz are shown in the table below:
