Figure 3: Power Supply Limits during Radio Transmission

To decrease voltage drop, a bypass capacitor of about 220µF with low ESR

(ESR=0.7Ω) should be used,

and a multi-layer ceramic chip capacitor (MLCC) array should also be reserved due to its ultra-low ESR. It

is recommended to use three ceramic capacitors (100nF, 33pF, 10pF) for composing the MLCC array,

and place these capacitors close to VCC pins. The main power supply from an external application has to

be a single voltage source. The width of VCC trace should be no less than 2mm. In principle, the longer

the VCC trace is, the wider it will be.

In addition, in order to get a stable power source, it is recommended to use a zener diode with reverse

zener voltage of 5.1V and dissipation power more than 0.5W. The following figure shows a reference

circuit of VCC.

3.3.2. Reference Design for Power Supply

Power design for the module is very important, as the performance of the module largely depends on the

power source. The power supply is capable of providing sufficient current up to 2A at least. If the voltage

drop between the input and output is not too high, it is suggested that an LDO should be used to supply

power for the module. If there is a big voltage difference between the input source and the desired output

(VCC), a buck converter is preferred to be used as the power supply.

The following figure shows a reference design for +5V input power source. The typical output of the power

supply is about 3.7V and the maximum load current is 3A.
