Description
The PKJ series is a High Density DC/DC Power Module providing over 90% efficiency in the industry standard half-brick format. To achieve this high efficiency, these modules use proprietary drive and control circuits with planar magnetics and low resistivity multilayer PCB technology, and a patented topology with active rectification.
The RFPA application specific PKJ are designed to provide high quality on-board power solution in Radio Frequency Power Amplifier systems as well as in other distributed power applications. The RFPA products are based on a mechanical design using metal to metal to attach the base plate, giving high thermal conductivity, good electrical isolation and excellent mechanical strength. The RFPA products electrical design is specifically adopted to fulfill RF load requirements.
The PKJ series also offers the flexibility of using a heatsink or cold wall mounting when needed, enabling reduced airflow, extended reliability or higher ambient temperature operation. The PKJ series include following standard features; output over-voltage protection, input under-voltage protection, over temperature protection, soft start, output short circuit protection, remote sense, remote control and output voltage adjust function.
