New Passive Devices
We are happy to announce the extension of our passive device family operating up to 110 GHz. Looking back on a long history of 110 GHz bias tees, DC-blocks, cable assemblies and connectors we have followed the request of our customers to provide fixed attenuators with the same outstanding performance and a variety of attenuation values.
Features
- Excellent flat frequency response from DC to 110 GHz
- Individual choice of attenuation values: 3, 6, 10 and 20 dB (other values on request)
- Different connector configurations available to avoid additional adapters in customer’s setup
- In-Series and Between-Series: 1.0 mm to 1.0 mm and 1.0 mm to 1.85 mm (the latter up to 65 GHz only)
- Compact design allows differential application with small connector spacing

Performance
The data sheet with all s-parameters of the 20 dB version is available now. The data sheets for further parts will follow shortly. The time domain performance is shown at a 200 Gbps PAM4 signal below.
