Pin Names and Descriptions
Description
Switch control for Rx mode
RF output is internally matched to 50 and DC blocked.
Ground connection
Power detector provides an output voltage proportional to the RF output power level.
Third stage bias voltage. This pin requires regulated supply for best performance.
Second stage bias voltage. This pin requires regulated supply for best performance.
First stage bias voltage. This pin requires regulated supply for best performance.
Power down pin. Apply <0.3V_DC to power down the three power amplifier stages. Apply 1.75V_DC to 5.0V_DC
to power up. If function is not desired, pin may be connected to VREG.
Ground connection
RF input is internally matched to 50 and DC blocked.
Ground connection
Ground connection
Supply voltage for the bias reference and control circuits.
This pin is connected internally to the collector of the 1st stage RF device. To achieve specified
performance, the layout of these pins should match the recommended land pattern.
Ground connection
This pin is connected internally to the collector of the 2nd stage RF device. To achieve specified
performance, the layout of these pins should match the recommended land pattern.
This pin is connected internally to the collector of the 3rd stage RF device. To achieve specified
performance, the layout of these pins should match the recommended land pattern.
