Product Description
The TriQuint TGA4502-SCC is a compact
High Power Amplifier MMIC for K-band
applications. The part is designed using
TriQuint’s proven standard 0.25 um gate
power pHEMT production process.
The TGA4502-SCC provides a nominal
29 dBm of output power at 1 dB gain
compression from 17-27 GHz with a small
signal gain of 22 dB.
The part is ideally suited for low cost
emerging markets such as K-band
Satellite Communications, Point-to-Point
Radio, and Point-to-Multi Point
Communications.
The TGA4502-SCC is 100% DC and RF
tested on-wafer to ensure performance
compliance.

These ratings represent the maximum operable values for this device. Stresses beyond those
listed under “Absolute Maximum Ratings” may cause permanent damage to the device and/or
affect device lifetime. These are stress ratings only, and functional operation of the device at
these conditions is not implied.
Junction operating temperature will directly affect the device median lifetime. For maximum life, it
is recommended that junction temperatures be maintained at the lowest possible levels.
