The PKJ4716APIHS delivers 28V at up to 25A\/700W, with an output voltage adjustment range of 14V to 35V, while the PKJ4716HPIHS delivers 50V at up to 14A\/700W, adjustable from 25V to 55V.<\/p>\n<p>The wide range of adjustability of the outputs makes them not only suitable for RFPA applications using LDMOS or GaN transistor technology, but also for other applications and markets that require a regulated programmable bus voltage such as 24V, 28V, 32V, 48V, 50V or 53\/54V, Test and Automation, and Industrial Control and Instrumentation, to name a few.<\/p>\n<p>\u201cThe PKJ4000 series is the first of a new expanded range of products we are developing for the RFPA market,\u201d explained Olle Hellgren, Head of Business and Product Management at Flex Power Modules. \u201cWe see great potential for us to bring the benefits of our leading-edge technology and efficiencies to this area as 5G continues its development and roll-out.\u201d<\/p>\n<p>Other product features of the PKJ4000 series include 1500V input\/output isolation, basic level insulation, monotonic start-up, remote sensing, remote control, and a range of protection capabilities including over-temperature, output-short-circuit and output-over-voltage.<\/p>\n<p>Offering a calculated MTBF figure of 7.5Mhrs, the new series has been designed and manufactured by Flex Power Modules to deliver the levels of quality and confidence that are required by power system designers to develop long-term and high-performance reliable platforms.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Efficiencies of up to 96.5% enable delivery of 700W in a half-brick format Flex Power Modules announced the release of the PKJ4000 series of DC\/DC converters primarily targeting radio frequency power amplifier (RFPA) applications within the telecom market segment.
