APPLICATION INFORMATION
Circuit Applications
External component requirements for the AWS5533 3. LESD provides a means to increase the ESD
are shown in Figure 8. Application details are listed protection on a specific RF port, typically the port
in the following notes:
attached to the antenna. By using LESD as an RF
choke on an RF port, an ESD protection to ±12 kV
contact discharge has been demonstrated.
1. Cb are DC blocking capacitors external to the device.
A value of 100 pF is sufficient for operation to 500 MHz.
The values may be tailored to provide specific electrical
responses.
2. The RF Ground connections should be kept as
short as possible and tied directly to a good RF
ground for best broadband performance.
