NOTE: Exceeding any one or a combination of the above maximum rating
limits may cause permanent damage. Input RF transients to +15dBm will
not harm the device. For sustained operation at inputs >+5dBm, a small
dropping resistor is recommended in series with the VCC in order to limit
the current due to self-biasing to <32mA.

Bias note: Due to the presence of ESD protection circuitry on the RF2370, the maximum allowable collector bias voltage (pin 4) is 4.0V.
Higher supply voltages such as 5V are permissible if a series resistor is used to drop VCC to <4.0V for a given ICC.
Caution! ESD sensitive device.
