DESCRIPTION AND APPLICATIONS

The FPD4000AS is a packaged depletion mode AlGaAs/InGaAs pseudomorphic High Electron

Mobility Transistor (pHEMT), optimized for power applications in L-Band. The surface-mount

package has been optimized for low parasitics.

Typical applications include drivers or output stages in PCS/Cellular base station transmitter

amplifiers, as well as other power applications in WLL/WLAN amplifiers.
