Key Features
Measured Performance
2 Watt C-Band Packaged Power Amplifier
The TriQuint TGA2706-SM is a packaged 2 Watt
Power Amplifier for C-band applications. The part
is designed using TriQuint’s proven standard
0.5um E/D pHEMT production process. The
TGA2706-SM provides a nominal 34 dBm of output
power at an input power level of 12 dBm with a
small signal gain of 31 dB. Nominal TOI is 42 dBm
and noise figure is 7 dB.
The TGA2706-SM is a QFN 5x5 mm surface
mount package. It is ideally suited for low cost
emerging markets such as point to point radio and
communications.
Lead-Free & RoHS compliant.
Evaluation boards are available upon request.

Assembly Notes
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.
