National RF, Inc
The National RF line of attenuators are compact, affordable attenuators which are ideal for insertion between a direction finding antenna and a receiver/transceiver, to aid in the DF process. In addition, they may be used in the laboratory for a low-power, in-line attenuation purposes. The affordable price is achieved by utilizing standard 5% tolerance resistors and commercial hardware. For laboratory purposes, an attenuation versus frequency curve (to 500mMHz) is provided.

Fairview Microwave Inc.
Our millimeter wave variable waveguide attenuators allow designers and engineers to test their systems at various signal strengths and attenuation values to determine the optimum signal performance of the system. The key feature of these waveguide attenuators is that the attenuation level is adjusted using a built-in micrometer which enables repeatable and rapid re-setting to different attenuation levels without the need for additional external components. Our waveguide attenuators handle varying attenuation levels from 0 to 30 dB over the specified band allowing the designer to tune the attenuation level needed for the application. These continuously variable waveguide attenuators cover a broad frequency range of 33 to 110 GHz in five bands and also display flat performance across a wide band with low insertion loss.

TYPE ATF -
National RF, Inc
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.

ERAVANT
Is a dual function direct reading and programmable rotary vane type attenuator for use in millimeterwave systems across the standard WR-03 frequency range of 220 to 330 GHz. The attenuator is an ideal piece of equipment in waveguide systems where a broad direct reading of attenuation is required. The default mode of operation is manual direct reading. In manual mode, the attenuation is adjustable with the large knob and the digital LCD screen displays the current attenuation value. The LCD screen is powered by an internal rechargable battery, which is charged via the 2.5mm DC jack by a provided DC to AC adapter. The 2.5mm DC jack also provides power to the stepper motor, encoder and internal microprocessor for the programmable mode function. The user can quickly switch to programmable mode by connecting the powered-up attenuator to a computer with the USB Type B port. In programmable mode, the attenuation is finely adjusted with a precision stepper motor by the internal microprocessor via user-entered serial port commands from the computer.

VF-145 LA AND VF-145 LMA -
National RF, Inc
The VF-145 LA and LMA models are functionally the same as the VF-145 L and LM on both electrical performance and mechanical specifications. However, the LA and LMA models include an internal PIN diode attenuator that provides up to 12 dB of attenuation (measured at 150 MHz, attenuation decrease slightly as operating frequency increases) to the incoming radio signal. This attenuation occurs after the signal is received by the unit and phase shifted for processing, but before it is placed on the coax feedline to the receiver. In addition, the PIN diode utilized will absorb short burst of RF should transceivers be keyed accidentally by the user. This feature aids in very strong signal DF operations but will not totally guarantee against system overload under very strong RF emissions.
