ATF-55143
Low Noise Enhancement Mode Pseudomorphic HEMT
in a Surface Mount Plastic Package
Data Sheet
Description
Avago Technologiesâ ATF-55143 is a high dynamic range,
very low noise, single supply E-PHEMT housed in a
4-lead SC-70 (SOT-343) surface mount plastic package.
The combination of high gain, high linearity and low
noise makes the ATF-55143 ideal for cellular/PCS hand-
sets, wireless data systems (WLL/RLL, WLAN and MMDS)
and other systems in the 450 MHz to 6 GHz frequency
range.
