ATF-54143
Low Noise Enhancement Mode Pseudomorphic HEMT
in a Surface Mount Plastic Package
Data Sheet
Description
Avago Technologies’ 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 gure
Excellent uniformity in product speci cations
800 micron gate width
Low cost surface mount small plastic package SOT-
343 (4 lead SC-70)
Tape-and-Reel packaging option available
Lead-free option available.
Speci cations
2 GHz; 3V, 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 gure
16.6 dB associated gain
Applications
Low noise ampli er 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.
