ATF-50189
Enhancement Mode[1] Pseudomorphic HEMT in
SOT 89 Package
Data Sheet
Description
Avago Technologies’s ATF-50189 is a high linearity,
medium power, low noise E-pHEMT FET packaged in
a low cost surface mount SOT89[3] package. The com-
bination of low noise figure and high output IP3 at
the same bias point makes it ideal for receiver and
transmitter application. Its operating frequency range
is from 400 MHz to 3.9 GHz.
Features
• High Linearity and P1dB
• Low Noise Figure
• Excellent uniformity in product specifications
• SOT 89 standard package
• Point MTTF > 300 years[2]
The ATF-50189 is ideally suited for Cellular/PCS and
WCDMA wireless infrastructure, WLAN, WLL and
MMDS application, and general purpose discrete
E-pHEMT amplifiers which require high linearity and
power. All devices are 100% RF and DC tested.
Notes:
1. Enhancement mode technology employs a single positive Vgs,
eliminating the need of negative gate voltage associated with
conventional depletion mode devices.
2. Refer to reliability datasheet for detailed MTTF data
3. Conform to JEDEC reference outline MO229 for DRP-N
4. Linearity Figure of Merit (LFOM) is OIP3 divided by DC bias power.
• MSL-1 and lead-free
• Tape-and-Reel packaging option available
Specifications
2 GH, 4.5V, 280 mA (Typ.)
• 45 dBm Output IP3
• 29 dBm Output Power at 1dB gain compression
• 1.1 dB Noise Figure
• 15.5 dB Gain
Pin Connections and Package Marking
• 62% PAE at P1dB
• LFOM[4] 14 dB

Applications
• Front-end LNA Q2 and Q3, Driver or Pre-driver Amplifier
for Cellular/PCS and WCDMA wireless infrastructure
• Driver Amplifier for WLAN, WLL/RLL and MMDS
applications
• General purpose discrete E-pHEMT for other high linearity
applications
