Fixed Attenuator
FAXE
-
Fixed Attenuators are waveguide components for introduction of some particular attenuation value in to the waveguide network for signal leveling or reflection compensation. The attenuators have two types of design: with resistive plate in the waveguide diagonal plane or using coupling technology. The FAXE 3, 6, 10, 15, 20, 30 dB attenuators are available in waveguide bands from 18 through 225 GHz. The FAXE Fixed Attenuators can be used as laboratory Standards against which other instruments or devices are calibrated in case the parameters of these Fixed Attenuators are stable enough and were measured with appropriate accuracy.

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.

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.
