Caution Although this device is designed to be as robust as possible, ESD (Electrostatic
Discharge) can damage this device. This device must be protected at all times from ESD. Static
charges may easily produce potentials of several kilovolts on the human body or equipment, which
can discharge without detection. Industry-standard ESD precautions must be employed at all times.

Notes 1. DC blocking capacitors = 1 000 pF at f = 0.05 to 0.5 GHz
2. Pin (0.1 dB) is the measured input power level when the insertion loss increases 0.1 dB more than that of
linear range.
Caution It is necessary to use DC blocking capacitors with this device.
The value of DC blocking capacitors should be chosen to accommodate the frequency of
operation, bandwidth, switching speed and the condition with actual board of your system. The
range of recommended DC blocking capacitor value is less than 100 pF for frequencies above
0.5 GHz, and 1 000pF for frequencies above 0.5 GHz.

: 0.5 to 3.0 GHz 56 pF
C2 : 1 000 pF
The application circuits and their parameters are for reference only and are not intended for use in actual design-ins.
APPLICATION INFORMATION
• LESD provides a means to increase the ESD protection on a specific RF port, typically the port attached to the
antenna.
• 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.
