Advance Product Information wwJwu.Dlyata2S9h,ee2t04U0.c5om 4 Watt 802.11a Packaged Amplifier TGA2921-SG Key Features • 4.9 - 6 GHz Application Frequency Range • 11 dB Nominal Gain @ 8V 800mA • 36 dBm Nominal P1dB @ 8V 800mA • 2.5% EVM at 26 dBm output power • IMD3 -50dBc @ 24dBm SCL, Typical • Bias Conditions: 7-9 V @ 700-800 mA (Quiescent) • 0.5 µm HFET Technology • 2 lead Cu base SMT package Primary Applications • 802.11a WLAN Bridge Amplifiers • U-NII Band HPA • C-Band Pt-Pt and Pt-Multi Pt Radio Product Description The TGA2921-SG HPA provides 11 dB of gain, 4 W of output power across 4.9 - 6 GHz and 2.5% EVM at 26 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.
