CB
• CB are DC blocking capacitors external to the device.
A value of 56 pF is sufficient for operation from 500 MHz to 2.5 GHz bands.
The value may be tailored to provide specific electrical responses.
• The RF ground connections should be kept as short as possible and connected to directly to a good RF ground
for best performance.
• LESD provides a means to increase the ESD protection on a specific RF port, typically the port attached to the
antenna.
