ATF-34143
Low Noise Pseudomorphic HEMT
in a Surface Mount Plastic Package
Data Sheet
Description
Avago’s ATF-34143 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-34143 is ideal for
the first stage of base station LNA due to the excellent
combination of low noise figure and high linearity^[1]. The
device is also suitable for applications in Wireless LAN,
WLL/RLL, MMDS, and other systems requiring super low
noise figure with good intercept in the 450 MHz to 10 GHz
frequency range.
Note:
1. From the same PHEMT FET family, the larger geometry ATF-33143
may also be considered either for the higher linearity performance
or easier circuit design for stability in the lower frequency bands
(800– 900 MHz).
