2.5

The O311 is a GaAs 6-bit digital phase shifter chip. The operating frequency is 2.5~3.7GHz, the insertion loss is less than 12.5dB, and the basic shift phase is -5.625°, -11.25°, -22.5°, -45°, -90°, -180°, and the total phase shift amount is -354.375°. The chip uses 0/-5V logic control, no external power supply bias, no power consumption. With excellent phase shift accuracy and port standing wave characteristics over the entire operating frequency range, it is ideally suited 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.
