Product Description
The TriQuint TGA4043 is a compact High
Power Amplifier MMIC for Q-band
applications. The part is designed using
TriQuint’s proven standard 0.25 um gate
power pHEMT production process.
The TGA4043 provides a nominal 28
dBm of output power at 1 dB gain
compression from 40-45 GHz with a small
signal gain of 10 dB.
The part is ideally suited for low cost
emerging markets such as Point-to-Point
Radio and Point-to-Multi Point
Communications.
The TGA4043 is 100% DC and RF tested
on-wafer to ensure performance
compliance.

NOTES
2/
These ratings represent the maximum operable values for this device.
Current is defined under no RF drive conditions. Combinations of supply voltage, supply
current, input power, and output power shall not exceed P
D
.
When operated at this power dissipation with a base plate temperature of 70 °C, the median
life is 7.3E3 hours.
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.
These ratings apply to each individual FET.
