MGA-43228

MGA-43228 (2.3–2.5) GHz 29dBm High Linearity Wireless Data Power Amplifier Data Sheet Description Avago Technologies’ MGA-43228 is a power amplifier for use in the (2.3-2.5)GHz band. High linear output power at 5V is achieved through the use of Avago Technologies’ proprietary 0.25um GaAs Enhancement-mode pHEMT process. It is housed in a miniature 5.0mm x 5.0mm x 0.85mm 28-lead QFN package. It also includes shutdown and switchable gain functions. A detector is also included on-chip. The compact footprint coupled with high gain and high efficiency make the MGA-43228 an ideal choice as a power amplifier for IEEE 802.16 (WiMAX) and WLL applications.
