Low Noise Enhancement Mode Pseudomorphic HEMT
in a Surface Mount Plastic Package
Avago Technologies’ ATF-58143 is a high dynamic
range, low noise 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-58143 ideal as low noise ampli-
fier for cellular/PCS/WCDMA base stations, wireless lo-
cal loop, and other applications that require low noise
and high linearity performance in the 450 MHz to 6 GHz
