The O222 is a GaAs monolithic integrated power amplifier chip operating at 8.0-12.0GHz delivering 21dB of power gain and 29dBm of saturated output power at + 8V operating power with an additional power efficiency of 30%.
The chip uses on-chip through-hole metallization process to ensure a good grounding, do not need additional grounding measures, easy to use. The back of the chip was metallized, suitable for eutectic sintering process.
