Bias note: Due to the presence of ESD protection circuitry on the RF2374, the maximum allowable collector bias voltage (pin 6) 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.

Bias note 2: In bypass mode, VREF is essentially a “don’t care” condition. Pulling VREF low when in bypass mode does conserve the small 1mA

to 2mA supplied by VREF.
