> 4 | Design Considerations

> As already mentioned above the switch frequency from a switched DC/DC converter might cause violation on the transmitter’s modulation spectrum.
> If the unit has to be able to work with input voltages such 30…40V it may be inconvenient to work with linear regulation.
> If you are not sure how to design a switched DC/DC converter that does not cause any trouble for the wireless module, and linear regulation is not suitable for your design, the following ideas might be helpful.
