P1048-QJ
General Description
The XP1048-QJ is a high linearity single stage power
amplifier capable of 13 dB of gain, 3 Watt of power at 1 dB
compression and is housed in a 6X6mm QFN package.
The XP1048-QJ provides less than 2.5% EVM at 27 dBm
output power with 802.16 OFDM signal and peak to
average power ratio of 9.17 dB. The input and output of the
device are pre-matched facilitating a simplified output
matching approach. The quiescent current is controlled
using a negative voltage.
The high dynamic range of this device makes it ideal as a
final or driver stage for WiMAX equipment in the 3.3-3.8
GHz bands.
