MGA-43328
MGA-43328 is 29dBm High Linearity Wireless Data Power Amplifier manufactured by Avago Technologies.
Description
Avago Technologies’ MGA-43328 is a power amplifier for use in the (2.5-2.7)GHz band. High linear output power at 5V is achieved through the use of Avago Technologies’ proprietary 0.25um Ga As Enhancement-mode p HEMT 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 pact footprint coupled with high gain and high efficiency make the MGA-43328 an ideal choice as a power amplifier for IEEE 802.16 (Wi MAX) and WLL applications.
