Abstract
A method for determining the switching frequency of a DC-to-DC power supply for a portable radio transceiver () includes determining a first group of switching frequencies () and then determining the switching harmonics based on that group of switching frequencies (). These switching harmonics are then compared to a group of desired radio channels () where it is then determined if the switching frequencies interfere with the group of desired radio channels (). Based on these results, a second group of switching frequencies is selected if the first set of switching frequencies provides an undesired level of interference ().
