POWER ATTENUATORS
TYPE ATF
-
National RF’s Type ATF Power Attenuators were designed to allow interfacing of linear power amplifiers to RF exciters, where a specific amount of drive to the amplifier is prescribed. Often, however, drive from the RF exciter exceeds this minimum prescribed level and some form of power attenuation must be used in order to not damage the input of the power amplifier. National RF’s type ATF-3 offers 3 dB of power attenuation (1/2 of the power) when used between the exciter and the amplifier and will handle an input power of 132 Watts, RMS (continuous power) while providing about 66 Watts RMS output power, when it is terminated into 50 ohms. In practice, the ATF-3 attenuator will handle exciters achieving Peak Envelope Power levels (PEP) in the area of 200 to 250 Watts while providing half of that power to the load. For less attenuation requirements, the ATF-1 and ATF-2 offer 1 and 2 dB of attenuation, respectively.

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.

High Voltage Pulse Attenuators
-
Barth High Voltage Pulse Attenuators are matched impedance coaxial attenuators for use primarily in pulsed 50 ohm systems, or where occasional transients would damage ordinary units. The attenuator design closely matches the impedance around each resistor, to that resistor. These attenuators feature an input impedance very close to 50 ohms, with characteristics as good or better than most microwave attenuators. These units are ideal for use in nuclear and high energy experiments. Extensive testing during manufacturing insures very high reliability for single-shot experiments. A voltage coefficient of the resistive film of less than .0001 %/V allows low voltage calibration of most systems.
