APPLICATION INFORMATION
Figure 9: Application Schematic
Circuit Applications
External component requirements for the
AWS5532R are shown in Figure 9. Application
details are listed in the following notes:
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.
3. L
ESD
provides a means to increase the ESD
protection on a specific RF port, typically the port
attached to the antenna. By using L
ESD
as an RF
choke on an RF port, an ESD protection to ±12 kV
contact discharge has been demonstrated.
4. The VS pin provides a fixed voltage potential to the
common port of the switch, and is not required for
normal operation (can be left open). To operate the
switch in an “all off” state (V1 = V2 = logic low), VS
should be tied to the logic high voltage potential (not
the power supply). Current draw on this pin is less
than 5 A.
