Product Description
The TriQuint TGA2803-SM is an ultra-
linear, packaged TIA/Gain Block
which operates from 40MHz to
1000MHz.
The TGA2803-SM typically provides
flat gain along with ultra-low distortion.
It also provides high output power with
low DC power consumption.

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.
