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:
