RF6535 Biasing Instructions
Tx Mode
• With the RF source disabled, apply 3.3V to V_CC with other controls set to 0V
• Apply 3.0V to SDN and 1.8V to CTL
• Apply 0V to ANT_SEL to select the ANT1 port, or 3.0V to select the ANT2 port
• V_CC current should rise to 70mA to 80mA quiescent current
• Enable the RF source; V_CC current should rise to a maximum of 200mA depending on output power
RX Mode
• With the RF source disabled, apply 3.3V to V_CC with other controls set to 0V
• Apply 3.0V to SDN, keeping CTL at 0V
• Apply 0V to ANT_SEL to select the ANT1 port, or 3.0V to select the ANT2 port
• V_CC current should rise to 7mA to 8mA
• Enable the RF source; V_CC current may increase a few mA depending on output power
