  • Power Conversion

    MaxLinear

    The XRP6124 is a non synchronous step down (buck) controller for up to 5A point of loads. A wide 3V to 30V input voltage range allows for single supply operations from industry standard 3.3V, 5V, 12V and 24V power rails. With a proprietary Constant On-Time (COT) control scheme, the XRP6124 provides extremely fast line and load transient response while the operating frequency remains nearly constant. It requires no loop compensation hence simplifying circuit implementation and reducing overall component count. The XRP6124 also implements an emulated ESR circuitry allowing usage of ceramic output capacitors and insuring stable operations without the use of extra external components.

  • Coaxial Switches

    Dow-Key Mircowave Corporation

    An electromechanical switch made primarily for routing microwave signals/RF energy from one point to another within a transmission line. Coaxial switches can be used in either an industrial environment or in the lab. These electromechanical devices are also used for RF testing equipment and in large RF communication systems and networks. Coaxial switches vary by port configuration, switch type, maximum frequency, isolation, insertion loss, voltage standing wave ratio (VSWR) and package type. Coaxial switches are able to route RF signals over a broad bandwidth from DC to 40 GHz, and are now offered with the Low PIM option which will improve Passive Intermodulation levels from -110dBc (standard switch) to -160dBc.
