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.
RoHS status based on EUDirective2002/95/EC (at time of this document revision).
The information in this publication is believed to be accurate and reliable. However, no

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 V
CC
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 V

to <4.0V for a given I
