MGA-43628
High Linearity (2.0 – 2.2) GHz Power Amplifier Module
Data Sheet
Description
Avago Technologies’ MGA-43628 is a fully matched power
amplifier for use in the (2.0-2.2) GHz band. High linear
output power at 5 V is achieved through the use of Avago
Technologies’ proprietary 0.25
m
GaAs Enhancement-
mode pHEMT process. MGA-43628 is housed in a miniature
5.0 mm x 5.0 mm molded-chip-on-board (MCOB) module
package. A detector is also included on-chip. The compact
footprint coupled with high gain, high linearity and good
efficiency makes the MGA-43628 an ideal choice as a
power amplifier for small cell BTS PA applications.
