ATF-50189
Enhancement Mode^[1] Pseudomorphic HEMT
in SOT 89 Package
Data Sheet
Description
Avago Technologies’s ATF-50189 is a high linearity, medi-
um power, low noise E-pHEMT FET packaged in a low cost
surface mount SOT89^[3] package. The combination 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.
The ATF-50189 is ideally suited for Cellular/PCS and WCD-
MA wireless infrastructure, WLAN, WLL and MMDS appli-
cation, 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
