General Description

TGA2703-SM is a linear amplifier
operating for 802.16 broadband
wireless applications in 3.3 to 3.8 GHz
frequency band. The PA delivers 24 dB
of small-signal gain, 30dBm P1dB and
40 dBc IMR3 at 21 dBm output power
per tone from a single +6V power
supply. It has 2.5% EVM at 22 dBm
output power. The TGA2703
incorporates a 13 dB step attenuator
function and a power sampling 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.

Note: This device is early in the characterization process prior to finalizing all electrical specifications. Specifications are subject to
change without notice.

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

Total current for the device.

When operated at this bias condition with a base plate temperature of 85

C, the median life is

reduced.

Junction operating temperature will directly affect the device median time to failure (MTTF). For
maximum life, it is recommended that junction temperatures be maintained at the lowest possible
levels.

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.
