Attenuators For Microwave Waveguides

A waveguide attenuator is an RF device specifically designed to reduce the power of a signal without affecting or reducing the waveform of the signal.

ATM manufactures waveguide attenuators in WG Sizes from WR650 thru WR28 covering a wide array of frequencies. We also offer high power and continuously variable  waveguide attenuators.

A waveguide attenuator works exactly opposite of an amplifier which increases the power of the signal without altering the waveform. Amplifiers provide an increase (or gain) in the power output whereas an attenuator provides a loss of power (or a gain less than 1).

Types of Waveguide Attenuators:

• Fixed Low Power Attenuator - Signal loss is constant and cannot be changed.
• Fixed Low Power Precision Attenuator - Signal loss is fixed and high precision elements are used.
• Fixed High Power Precision Attenuator- Precision elements yield optimum electrical performance at high power.
• Continuously Variable Attenuator - Also known as CVA, where the signal loss can be changed using a mechanical adjustment screw, knob or dial.
