“4P” = Device code
“x” = Date code character. A new
character is assigned for each month, year.
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).
