Study on the Impact of Operating Point on Transmission Efficiency and Harmonic Suppression of T/R Module Based on Wide Bandgap Semiconductor

摘要：

Focusing on the Impact of Operating Point to Transmission Efficiency and Harmonic Suppression of T/R Module Based on Wide Bandgap Semiconductor,this paper theoretically analyzes the relation between operating point and transmission efficiency and linearity.Experiment of GaN T/R module based on GaN HEMT NPTB0004 shows that with optimal static current of 50mA,transmission PAE is up to 45.5% and suppression of second harmony is better than 21dBc,and suppression of third harmony is better than -15dBc. This can supply engineering value of active phase array radar for SAR application.
