Notes:

Exceeding the absolute maximum rating may damage the device.

The device is not guaranteed to function outside of its operating rating.

Device is ESD sensitive. Use appropriate ESD precautions. Human body model, 1.5

kΩ in series with 100pF.

4. In an ON/OFF keyed (OOK) signal, the signal level goes between a “mark” level (when the RF signal is ON) and a “space” level (when the RF signal

is OFF). Sensitivity is defined as the input signal level when “ON” necessary to achieve a specified BER (bit error rate). BER measured with the

built-in BERT function in Agilent E4432B using PN9 sequence. Sensitivity measurement values are obtained using an input matching network to

433.92MHz.
