ATF-33143
Low Noise Pseudomorphic HEMT
in a Surface Mount Plastic Package
Data Sheet
Description
Avago’s ATF-33143 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-33143 is ideal for
the first or second stage of base station LNA due to the
excellent combination of low noise figure and enhanced
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 smaller geometry ATF-
34143 may also be considered for the higher gain performance,
particularly in the higher frequency band (1.8 GHz and up).
