NOTE: Exceeding any one or a combination of the above maximum rating lim-

its 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.

Caution! ESD sensitive device.

Exceeding any one or a combination of the Absolute Maximum Rating conditions may

cause permanent damage to the device. Extended application of Absolute Maximum

Rating conditions to the device may reduce device reliability. Specified typical perfor-

mance or functional operation of the device under Absolute Maximum Rating condi-

tions is not implied.

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.
