The ADRF5420 has two power supply pins (VDD and VSS) and

one control pin (CTRL). Figure 17 shows the external components

and connections for the supply pin. The VDD, VSS, and CTRL

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 RF 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.
