Agilent ATF-55143 Low Noise
Enhancement Mode
Pseudomorphic HEMT in a
Surface Mount Plastic Package
Data Sheet
Description
Agilent Technologies’s ATF-55143
is a high dynamic range, very low
noise, single supply E-PHEMT
housed in a 4-lead SC-70
(SOT-343) surface mount plastic
package.
The combination of high gain,
high linearity and low noise
makes the ATF-55143 ideal for
cellular/PCS handsets, wireless
data systems (WLL/RLL, WLAN
and MMDS) and other systems in
the 450 MHz to 6 GHz frequency
range.
Features

specifications
• 400 micron gate width
• Low cost surface mount small
plastic package SOT-343 (4 lead
SC-70)
• Tape-and-Reel packaging option
available
Specifications
2 GHz; 2.7V, 10 mA (Typ.)
• 24.2 dBm output 3
rd
order intercept
• 14.4 dBm output power at 1 dB
gain compression
• 0.6 dB noise figure
• 17.7 dB associated gain
Applications
• Low noise amplifier for cellular/
PCS handsets
• LNA for WLAN, WLL/RLL and
MMDS applications
• General purpose discrete E-PHEMT
for other ultra low noise applications
Note:
1. Enhancement mode technology requires
positive Vgs, thereby eliminating the need for
the negative gate voltage associated with
conventional depletion mode devices.
