Product Description
The TriQuint TGA2704 is a High Power
Amplifier MMIC for 9 – 10.5GHz applications.
The part is designed using TriQuint’s 0.25um
3MI pHEMT production process.
The TGA2704 nominally provides 38 dBm
output power and 40% PAE for bias of 9V,
1.05A. The typical gain is 20 dB.
The part is ideally suited for low cost markets
such as Point-to-Point Radio and
Communications.
The TGA2704 is 100% DC and RF tested on-
wafer to ensure performance compliance.
The TGA2704 has a protective surface
passivation layer providing environmental
robustness.
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
.
Total current for the entire MMIC.
When operated at this power dissipation with a base plate temperature of 70 °C, the median life
is 2.3E4 hrs.
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.
