​220-260 GHz Down Converters for 5G/6G Applications

Signal generators, spectrum analyzers, and Vector Network Analyzers (VNA) may be extended seamlessly to millimeter-wave and Terahertz (THz) frequencies. These instruments can measure Noise Figure accurately, utilizing compatible noise sources for precise results. The Block Up/Downconverter function, when combined with external sources, ensures optimal performance. In the frequency range of 75-500 GHz, our solutions offer both full-band and narrow-band options with an optional internal local oscillator. For enhanced signal purity, a Single Sideband (SSB) version will eliminate image responses. These Multifunction Converters offer rugged screened enclosures machined from solid, guaranteeing durability and reliability in challenging environments. Meet your high-frequency testing and measurement requirements with precision and versatility.
