Surface Mount Package - SOT-343
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
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
Pin Connections and Package Marking
may also be considered either for the higher linearity performance
or easier circuit design for stability in the lower frequency bands
(800– 900 MHz).
Note: Top View. Package marking provides
orientation and identification.

Noise Parameter Applications Information F values at 2 GHz and higher are based on measure- min ments while the F below 2 GHz have been extrapo- mins lated. The F values are based on a set of 16 noise figure min measurements made at 16 different impedances using an ATN NP5 test system. From these measurements, a true F is calculated. F represents the true minimum noise min min figure of the device when the device is presented with an impedance matching network that transforms the source impedance, typically 50Ω impedance represented by the reflection coefficient Γ . The designer must design o a matching network that will present Γ minimal associated circuit losses. The noise figure of the completed amplifier is equal to the noise figure of the device plus the losses of the matching network preceding the device. The noise figure of the device is equal to F ...
