Description
Agilent’s ATF-35143 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 perfor-
mance, ATF-35143 is suitable for
applications in cellular and PCS
base stations, LEO systems,
MMDS, and other systems requir-
ing super low noise figure with
good intercept in the 450 MHz to
10 GHz frequency range.
Other PHEMT devices in this
family are the ATF-34143 and the
ATF-33143. The typical specifica-
tions for these devices at 2 GHz
are shown in the table below:
