General Description
TGA2702-SM is a linear amplifier
operating for 802.16 fixed broadband
wireless applications across the 2.3 to
2.8 GHz frequency band. Application
include WiMAX, 802.11g and WiBro.
The PA delivers 28 dB of small-signal
gain and Pout of 23dBm @ 2.5% EVM
(2.6GHz 802.11g OFDM waveform)
from a single +6V power supply. The
TGA2702 incorporates an 16 dB step
attenuator function and a power sample
port. The 50 ohm device requires
minimum external components for
operation, and is packaged in a low-
cost, surface mount 5x5 QFN style
package.
Lead-Free & RoHS compliant
Demo boards are available.
