GaAs Monolithic Integrated Switch O125

GaAs Monolithic Integrated Switch O125

0 out of 5

O125 is an absorption GaAs pHEMT single-pole, eight-throw switch chip, operating frequency covering DC ~ 35GHz. The switch chip provides greater than 30dB isolation and less than 3.3dB insertion loss over the entire operating frequency range. Built-in 2:4 decoder, using -5V + TTL control. Ideal 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.
