Functional Block Diagram
General Description
TriQuint’s TGA2612-SM is a packaged broadband Low
Noise Amplifier fabricated on TriQuint’s TQGaN25
0.25um GaN on SiC process. Covering 6–12 GHz, the
TGA2612-SM typically provides >23 dM small signal
gain, 19 dBm P1dB, and 27 dBm OTOI with <2 dB of
Noise Figure.
In addition to the high electrical
performance, this GaN amplifier also provides a high
level of input power robustness. Able to survive up to
2W of input power without performance degradation,
TriQuint’s TGA2612-SM provides flexibility regarding
receive chain protection resulting in lower costs and
reduced board space.
The TGA2612-SM is available in a surface mount 20-
lead 4x4mm QFN. It is ideally suited for both radar and
communications applications.
Fully matched to 50 ohms with integrated DC blocking
caps on both I/O ports, the TGA2612-SM is ideally
suited for both military and commercial radar and
communications applications.
Lead-free and RoHS compliant
Evaluation Boards are available upon request.
