QBE Frequency Extenders

Product Description

QuinStar Technology's series QBE frequency extenders utilize a chain of passive or active multipliers and amplifiers to extend a microwave source to cover the frequency range of 18 to 110 GHz. The extenders also allow the use of network analyzers, sweepers and synthesizers operating in the 2-20 GHz range to frequencies in the 20-110 GHz range. Multiplication factors of 2 to 12 are available and integral filters guarantee low spurious levels.

Both full waveguide bandwidth/moderate output power and narrow bandwidth/high output power versions are available. The standard product has all extender components integrated and mounted on a baseplate. Typically, input is a coaxial SMA-F or K connector and output is waveguide. Other RF interface configurations are available.
