Amplified Switched Filter Bank
Lexatys’ new three-channel amplified Switched Filter Bank has stopbands extending beyond 40 GHz to help eliminate undesired harmonics. With a compact size of 1.08 × 0.54 × 0.24 in. and paired with high speed switching between channels, the Filter Bank has a low profile with high impact. It features a solderless interconnect to help reusability within prototype assemblies to allow performance to be evaluated before being integrated into the design. This part is also compatible with the X-Microwave prototyping system.
