Agilent ATF-54143 Low Noise
Enhancement Mode
Pseudomorphic HEMT in a
Surface Mount Plastic Package
Data Sheet
Description
Agilent Technologies’s ATF-54143
is a high dynamic range, low
noise, 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-54143 ideal for
cellular/PCS base stations,
MMDS, and other systems in the
450 MHz to 6 GHz frequency
range.
Features
• High linearity performance
• Enhancement Mode Technology
[1]
• Low noise figure
• Excellent uniformity in product
specifications
• 800 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; 3 V, 60 mA (Typ.)
• 36.2 dBm output 3
rd
order intercept
• 20.4 dBm output power at 1 dB
gain compression
• 0.5 dB noise figure
• 16.6 dB associated gain
Applications
• Low noise amplifier for cellular/
PCS base stations
• 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.
