Abstract

The architecture for the JEDI Cenelec, intrinsically safe radio is based around a special battery which provides a dual voltage source, a high voltage, high current supply for the RF power amplifier and a lower voltage, lower current supply for the remainder of the circuitry (Figure 1). It is useful, important and indeed, safety-critical, to be able to indicate to the user that the correct battery has been fitted before the radio is placed into service.
