Attenuators
OZ Optics offers a broad range of both variable and fixed attenuators having key competitive advantages. All of our attenuators operate over the two standard wavelength bands, the C-Band and the L-Band. This wide wavelength range makes these components ideal for DWDM applications. Our attenuators are wavelength insensitive, which means they operate with minimal changes in attenuation when used in either the C-Band or the L-Band and exhibit low return loss. In addition, all of our attenuators have a wide attenuation range, which means they operate at a wide range of power levels. This is important as increased power levels are being used in newer optical systems.

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.

Attenuators And Pulse Limiters
A bidirectional attenuator, i.e. the attenuation and power capability specification is valid for both directions. There is a large variety of applications for this attenuator: The measuring range of a spectrum analyzer can be increased. Any kind of meter can be protected against overload; it can be used to control the linearity of a meter reading. It can minimize measurement uncertainty caused by mismatched impedances. During an EMI receiver calibration an attenuator directly at the pulse generator output is inevitable.
