Modular Frequency Extenders for Vector Network Analyzers

Modular frequency extenders will be developed for Vector Network Analyzers to extend their frequency range throughout the band from 100 GHz through 1THz with excellent dynamic range (100dB) and the capability for full four port measurements. The extenders will rely on VDI's full waveguide band frequency multipliers and mixers that utilize planar, integrated Schottky diode circuits. The modular nature of the system will allow rapid reconfiguration of the components for operation in any of the waveguide bands within a few minutes, while maintaining low cost through the use of the same driver components. In Phase 1 VDI will demonstrate one of the waveguide bands with the required level of performance and the modular nature of the system. This will include the development and demonstration of all of the critical components and the delivery of this extender to the sponsor. This system will serve as a prototype for the commercial sale of VNA extenders for the wider commercial market including national, industrial and university research laboratories that are developing new applications and technologies for this important frequency band.
