20 - 40 GHz 2 Watt GaN Power Amplifier: QPA2040D Datasheet

The QPA2040D is a Ka-band power amplifier fabricated on 0.15um GaN on SiC process (QGaN15). Operating between 20 and 40GHz, it achieves saturated output power of 2W with power-added efficiency of 13%. To simplify system integration, the QPA2040D is fully matched to 50 ohms with integrated DC blocking caps on both RF I/O ports. The RF input is DC blocked, and the RF output is a DC short. The QPA2040D is 100% DC and RF tested on-wafer to ensure compliance to electrical specifications.
