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.
| Model | Frequency range, GHz | Waveguide size | Attenuation range, dB | VSWR | Insertion loss, dB |
| VA-06E | 33 - 50 | WR - 22 | 0÷30 | 1,15 | 0,5 |
| VA-04E | 50 - 75 | WR - 15 | 0÷30 | 1,15 | 0,5 |
| VA-035E | 60 - 90 | WR - 12 | 0÷30 | 1,2 | 0,7 |
| VA-03E | 75 - 110 | WR - 10 | 0÷30 | 1,2 | 0,7 |
| VA-025E | 90 - 140 | WR - 8 | 0÷30 | 1,2 | 1,0 |
| VA-02E | 110 - 170 | WR - 6 | 0÷30 | 1,2 | 1,0 |
| VA-015E | 140 - 220 | WR - 5 | 0÷30 | 1,2 | 1,0 |
