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