Waveguide Variable Attenuators

For perfect matching sometimes it is required that the microwave power in a waveguide be absorbed completely without any reflection and also insensitive to frequency. For this attenuators are used. Attenuators are commonly used for measuring power gain or loss in dBs for providing isolation between instruments, for reducing the power input to a particular stage to prevent overloading. Scientific Microwave offers fixed and variable attenuator-s to its customers. Variable Attenuators These attenuators provide continuous attenuation of power upto 20 dB.
