Product Description

QuinStar Technology’s series QBE Frequency Extenders utilize a chain of passive or active frequency multipliers, amplifiers and filters to extend microwave signal generators to cover frequency ranges of 18 to 110 GHz. These extenders also extend the operation of microwave network analyzers, sweepers and synthesizers operating in the 2-20 GHz range to millimeter wave frequencies in the 18 to 110 GHz range. Frequency multiplication factors of 2 to 12 are available, and use of waveguide filters guarantees low spurious levels and very low harmonics of the microwave signal. Models covering full waveguide bands with input power of 10 dBm are offered as standard products. Also, models with higher output power levels up to 20 dBm are available over full or partial bands. Series QBE Frequency Extenders are packaged in a rugged enclosure typically with a coaxial SMA-F or K connector input and a waveguide output. However, these can be provided with the entire assembly mounted on a baseplate.
