9.6 mm Discrete HFET TGF4260-SCC
Key Features and Performance
9600 m x 0.5 m HFET
Nominal Pout of 37dBm at 6 GHz
Nominal Gain of 9.5dB at 6 GHz
Nominal PAE of 52% at 6 GHz
Frequency Range: DC - 10.5 GHz
Suitable for high reliability applications
0.6 x 2.4 x 0.1 mm (0.024 x 0.093 x 0.004 in)
Description
The TriQuint TGF4260-SCC is a single gate 9.6 mm discrete GaAs Heterostructure
Field Effect Transistor (HFET) designed for high efficiency power applications up to
10.5 GHz in Class A and Class AB operation.
Typical performance at 6 GHz is 37dBm power output, 9.5 dB Gain, and 52% PAE.
Bond pad and backside metallization are gold plated for compatibility with eutectic
alloy attach methods as well as thermocompression and thermosonic wire bonding
processes.
The TGF4260-SCC is readily assembled using automatic equipment.
Primary Applications
Cellular Base Stations
High-reliability space
Military

1/ These ratings represent the maximum values for this device. Stresses beyond those listed
under "Maximum Ratings" may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other conditions beyond
those indicated under "DC Probe Characteristics" is not implied. Exposure to maximum rated
conditions for extended periods may affect device reliability.
2/ When operated at this bias condition with a base plate temperature of 70
0
C, the MTTF life is
reduced from 1.7 E+12 to 3 E+9 hours.
3/ Junction temperature will directly affect the device Mean Time to Failure (MTTF). For
maximum life, it is recommended that junction temperatures be maintained at the
lowest possible levels
4/ These ratings apply to each individual FET
