DESCRIPTION AND APPLICATIONS
The FPD4000AF is a packaged depletion mode AlGaAs/InGaAs pseudomorphic High Electron
Mobility Transistor (pHEMT), optimized for power applications in L-Band. The high power flange-
mount package has been optimized for low electrical parasitics and optimal heatsinking.
Typical applications include drivers or output stages in PCS/Cellular base station transmitter
amplifiers, as well as other power applications in WLL/WLAN amplifiers.
