typically measured as 500V using MIL-STD-883 method
3015. Therefore, ESD handling precautions are essential to
avoid degradation of performance or permanent damage of
this device.
ELECTRICAL CHARACTERISTICS
NOTES
1. The RSSI output is 100% dynamically tested at 5V and 20°C over a 70dB range. First the input to pin 13 is set to 2·5mV and the RSSI current
2. Co-channel rejection is measured by applying a 3kHz deviation, 1kHz modulated signal at an input level to give a 20dB SINAD ratio. Then

a 3kHz deviation 400Hz modulated slgnal on the same frequency is also applied and its level increased to degrade the SINAD to 14dB.
