High-Voltage DC Power Supplies
-
Higher-voltage and Higher-power Supplies require more complex design solutions. The heat to be dissipated and installation infrastructure, plus choice of insulation system in a HVPS are driven by the output voltage and output power which ultimately dictates packaging. Typical insulation systems are based on air, dielectric oil, epoxy, RTV Silicone and even Sulfur Hexafluoride (SF6). The method of cooling is a factor as well, the choices often coming down to air, water or oil, depending on the platform design requirements. These applications require Excelitas' detailed understanding to help choose the best design solution.

Low Voltage DC / Battery Powered HV Amplifiers
WMA-01 And WMA-01LF
-
The Falco Systems WMA-01 is a high voltage amplifier that runs from an 24 - 30V DC power supply and can be battery powered if required, e.g. for use in a Faraday cage. Its internal high voltage generator is inductor-free and hence does not spread magnetic interference in sensitive experimental setups. The output noise is impressively low at 3mVrms. For extremely low noise applications where bandwidth is not an issue, a dedicated WMA-01LF version is available that contains an output low pass filter capacitor which reduces the bandwidth to 50Hz, but makes the noise drop to below 0.1mVrms. This bandwidth-limited amplifier is ideal for MEMS or piezo positioning with manual voltage adjustment.

DC Measurements
-
Standard Windows sound cards do not respond to DC or frequencies lower than a few Hz. (See Why Sound Cards Block DC Signals below for explanation.)There are two general approaches to get true DC response from a standard sound card: Modify the card, or add an external circuit to convert the DC into an AC signal which can be easily measured by an unmodified card.

Programmable Step Attenuator, DC to 26.5 GHz, 90 dB, 10 dB steps
84906K
Attenuator
The Keysight 84906K programmable step attenuator offers coaxial measurements to 26.5 GHz in a compact, rugged design. It offers repeatability of better than 0.03 dB, excellent life (greater than 5 million switching cycles per section) and an attenuation range of 0 to 90 dB in 10-dB steps. This latest design evolution sets new standards for size and performance. High attenuation accuracy and low SWR are achieved through the use of miniature thin-film attenuation cards composed of high-stability tantalum nitride film of saphire substrate. Insertion loss is outstanding, with less than 2 dB of loss at 26.5 GHz. The compact size of the unit, 35 percent smaller than the Keysight 8495/7 (26.5 GHz) family, allows for easy integration into instruments and ATE systems.
