Agilent ATF-58143 Low Noise
Enhancement Mode
Pseudomorphic HEMT in a
Surface Mount Plastic Package
Data Sheet
Description
Agilent Technologies’s
ATF-58143 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-58143 ideal as
low noise amplifier for cellular/
PCS/WCDMA base stations,
wireless local loop, and other
applications that require low
noise and high linearity perfor-
mance in the 450 MHz to 6 GHz
frequency range.
Features
• Low noise and high linearity
performance
• Enhancement Mode Technology
[1]
• Excellent uniformity in product
specifications
• Low cost surface mount small
plastic package SOT-343 (4 lead
SC-70) in Tape-and-Reel packaging
option available
• Lead-free option available
Specifications
2 GHz; 3V, 30 mA (Typ.)
• 30.5 dBm output 3
rd
order intercept
• 19 dBm output power at 1 dB
• 0.5 dB noise figure
• 16.5 dB associated gain
Applications
• Q1 LNA for cellular/PCS/WCDMA
base stations
• Q1, Q2 LNA and Pre-driver
amplifier for 3–4 GHz WLL
• Other low noise and high linearity
applications at 450 MHz to 6 GHz
Note:
1. Enhancement mode technology requires
positive Vgs, thereby eliminating the need for
the negative gate voltage associated with
conventional depletion mode devices.
