Modular Frequency Extenders for Vector Network Analyzers

Modular system will be developed to extend the frequency range of Vector Network Analyzers to at least 1 THz. These extenders will offer excellent dynamic range and stability, as well as the capability for fully calibrated measurements. The extenders will rely on innovative full waveguide band frequency multipliers and mixers that utilize planar, integrated Schottky diode circuits. The modular extender systems will allow rapid reconfiguration of the components for operation in multiple waveguide bands, while maintaining low cost. During Phase 1 VDI demonstrated the modular extender concepts and delivered a WR2.2 frequency extender with exceptional dynamic range and excellent stability. Phase 2 will emphasize the development of modular extenders for the complete 100GHz to 1,000GHz frequency band. This includes development of the individual components that most affect system performance, as well as the development of the extender systems to yield reliable and cost effective products. The deliverable system, covering 100GHz to 1,000GHz, will serve as a prototype for the sales of VNA extenders for the wider commercial market; which includes national, industrial and university research laboratories that are developing new technologies and applications for the terahertz frequency band.
