Cautions
- It can be used in clean environment;
- GaAs material is very brittle, and the surface of the chip is easy to be damaged, so we should be careful when using it;
- Two bonding wires (25um gold wire in diameter) are used for input and output, and the bonding wire is as short as possible (less than400um);
- The input and output have no blocking capacitance;
- The sintering temperature is lower than 300 ℃ and the sintering time is as short as possible, less than 30seconds;
- This product belongs to electrostatic sensitive device, pay attention to anti-static when storing and using;
- Storage in dry nitrogen environment.
