Artesyn Embedded Technologies produces a growing range of isolated DC-DC converters that are designed specifically to produce the regulated low noise DC supply for RF power amplifiers in wireless base stations and similar telecommunications applications. Most of these converters have a nominal 28 Vdc or 48Vdc output and are typically used in conjunction with one or more other isolated converters to generate the other lower voltages required for wireless applications, beyond that required of the power amplifier.

All of our DC-DC converters for RF applications are very high efficiency, high power density designs with industry-standard 2.3 x 0.9 inch (56.1 x 23 mm) eighth-brick, 2.4 x 2.3 inch (61 x 58 mm) half-brick or 2.4 x 4.6 inch (61 x 117 mm) full-brick footprints. For optimum thermal performance each converter is available with an aluminum baseplate structure that helps to simplify cooling arrangements, with optional threaded or non-threaded inserts.To further expedite design-in, all of the converters that we produce for this specialist market have a 2:1 input voltage range of either 36 to 75 Vdc (nominally 48 V) or 18 to 36 Vdc (nominally 24 V).
