What is a 50 ohm attenuator?
The frequency range of our 50 Ohm fixed attenuators is from DC to 50 GHz. This product line includes low to high power attenuators which have the power handling up to 500 Watts. Pasternack 50 Ohm fixed attenuators include male and female genders and can be bidirectional and directional, depending on the power rating.
How do you test RF attenuator?
Several different methods can be used to check the accuracy of an attenuator or a single pad. The simplest method is to use an ohmmeter to check the resistance. The resistance of an attenuator or pad designed for a 50 ohm system will show the same resistance on either side because they are of a symmetrical design.
What does attenuator mean?
: a device for attenuating especially : one for reducing the amplitude of an electrical signal without appreciable distortion.
What is the attenuation in dB assuming i1 is the input current and i2 is the output current leaving the port?
Explanation: Assuming I1 is the input current and I2 is the output current leaving the port, the attenuation in dB is Attenuation in dB = 20 log10 (I1/I2) where I1 is the input current and I2 is the output current leaving the port.
Which is the best attenuator for variable RF?
The bridged T attenuator pad is often the favoured format for variable RF attenuators, especially those using PIN diodes. The reason for this is that the bridged T attenuator pad only requires the use of two variable resistors against the three required for both the Pi and T attenuator pads.
What are the resistances of AVX RF resistors?
AVX produces high power RF/Microwave resistors, terminations and attenuators designed to withstand up to 250W of continuous power, with resistances ranging from 10Ω to 200Ω and available constructions in chip, surface mount, leaded and flange mount packages.
Which is the opposite of the Pi section resistive attenuator?
T attenuator pads: In terms of topology the T attenuator pad (or Tee attenuator pad) is the opposite of the Pi section resistive attenuator, but it performs equally as well. This form of RF attenuator has two resistors in series with each other between the input and the output.
Which is a high resistance or low resistance attenuator?
At high attenuation levels R5 is at a high resistance and R6 is low. Accordingly the predominant resistor values at those labelled R which is equal to the characteristic impedance. When undertaking the RF design of an attenuator there are several points that should be considered if the best performance is to be achieved.
