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).
