The O599 is a GaAs monolithic integrated bi-directional amplifier chip operating from 3.0-7.0GHz. It operates from a single +5V supply and provides 21dB gain and 18dBm P1dB output power at 80mA operating current. The bi-directional amplifier chip adopts an on-chip via hole metallization process to ensure good grounding, no additional grounding measures are needed, and the use is simple and convenient. The backside of the chip is metallized and suitable for eutectic sintering or conductive adhesive bonding processes.
