The ADRF5440 has two power supply pins (VDD and VSS) and

two digital control pins (V1 and V2). Figure 25 shows the external

components and connections for the supply pins. The VDD, VSS,

V1, and V2 pins are decoupled with a 100pF multilayer ceramic

capacitor. The device pinout allows the placement of the decoupling

capacitors close to the device. No other external components are

needed for bias and operation, except DC blocking capacitors on

the RFx pins when the RF lines are biased at a voltage different

than 0V. Refer to the Pin Configuration and Function Descriptions

section for further details.
