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 Pointto-Point or Point-to-Multi Point NonLine 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.

These ratings represent the maximum operable values for this device. Combinations of supply voltage, supply current, input power, and output power shall not exceed P D. When operated at this bias condition with a base plate temperature of 85 C, the MTTF life is 2 E+8 hours. Junction operating temperature will directly affect the device median time to failure (TM). For maximum life, it is recommended that junction temperatures be maintained at the lowest possible levels.

Bias Procedure 1. 2. 3. 4. 5. Ensure no RF power is applied to the device. Pinch off device by setting Vg to -3V. Increase Vd to 8.0V while monitoring drain current. Increase Vg until drain current reaches 480 mA. Apply RF power.
GaAs MMIC devices are susceptible to damage from Electrostatic Discharge. Proper precautions should be observed during handling, assembly and test.

Recommended Surface Mount Package Assembly
Proper ESD precautions must be followed while handling packages. Clean the board with acetone. Rinse with alcohol. Allow the circuit to fully dry. TriQuint recommends using a conductive solder paste for attachment. Follow solder paste and reflow oven vendors' recommendations when developing a solder reflow profile. Typical solder reflow profiles are listed in the table below. Hand soldering is not recommended. Solder paste can be applied using a stencil printer or dot placement. The volume of solder paste depends on PCB and component layout and should be well controlled to ensure consistent mechanical and electrical performance. Clean the assembly with alcohol.
