Product Description
The TGA2922-SG HPA provides
11dB of gain, 2 W of output power
across 4.9 - 6 GHz and 2.5% EVM
at 25 dBm output power. The device
is ideally suited for high linearity,
high power wireless data
applications such as 802.11a WLAN
Bridge Amplifiers, U-NII and Point-
to-Point or Point-to-Multi Point Non-
Line of Sight radios. The package
has a high thermal conductivity
copper base. Internal partial
matching simplifies system board
layout by requiring a minimum of
external components.
Lead-Free & RoHS compliant.
Evaluation Boards are available.
