The O251 is a GaN monolithic integrated power amplifier chip operating at 5.0-6.5GHz. It provides 22dB power gain and 36dBm saturated output power at a continuous wave, +28V operating voltage, and a power-added efficiency of 48%.
The chip uses on-chip via metallization process to ensure a good grounding, no additional grounding measures, easy to use. The backside of the chip is metallized and is suitable for eutectic sintering processes.
