General Description
The TriQuint T1G2028536-FL is a 285 W (P
3dB
) discrete
GaN on SiC HEMT which operates from DC to 2 GHz.
The device is constructed with TriQuint’s proven
TQGaN25HV process, which features advanced field
plate techniques to optimize power and efficiency at high
drain bias operating conditions. This optimization can
potentially lower system costs in terms of fewer amplifier
line-ups and lower thermal management costs.
Lead-free and ROHS compliant
Evaluation boards are available upon request.
