Variable attenuator
- Wide attenuation range
- Low VSWR
- Low insertion losses
- Full waveguide bandwidth
The VAXE Variable Attenuators are waveguide components for tunable signal leveling or reflection compensation in waveguide networks. The Attenuators consist of waveguide section with a resistive film evaporated on the mica surface. The Attenuators has 0 ÷30 dB minimum attenuation range. The VAXE Attenuators are available in four waveguide bands between 33 GHz and 170 GHz.
