O129 is a reflective gallium arsenide pHEMT single-pole double-throw switch chip, operating frequency covering DC ~ 40GHz. The switch chip can provide less than 2.5dB insertion loss and more than 25dB isolation across the operating frequency band. Use 0/-5V logic control, no external power supply bias, no power consumption. It is often suitable for microwave hybrid integrated circuits and multi-chip modules as well as low-power systems.
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 suitable for eutectic sintering or conductive adhesive bonding processes.
