General Description

SAC3209AQ3 is a broadband reflective GaAs PHEMT single pole single throw switch chip, covering the frequency band DC ~ 20GHz. The chip provides isolation of more than 50dB and insertion loss of less than 1dB in the whole working frequency band. The bias voltage is -4.5V, which is controlled by 0 / + 5V logic. It has excellent switching characteristics and port standing wave characteristics in the working frequency band. It is suitable for microwave hybrid integrated circuits, multi chip modules and low power systems.
The switch chip adopts on chip through hole metallization process to ensure good grounding. The back of the chip is metallized, which is suitable for eutectic sintering or conductive adhesive bonding process.
