QuinStar Technology, Inc. Noise Source QNS

Description
QuinStar Technology’s QNS series of millimeter-wave noise sources cover the frequency range of 50 to 110 GHz in three waveguide bands with up to full standard wave-guide band coverage. They feature stable noise power output, high switching speed and relatively flat high output power. Careful device selection, special cavity design and matching circuits have all contributed to a reliable design that is highly stable with time and over temperature. The noise output power of these noise sources is specified in terms of excess noise power ratio (ENR) as a function of frequency. QuinStar Technology offers three versions of these noise sources to suit virtually any application. Full waveguide band noise sources are offered for use with Noise Figure Meters. These models provide very flat ENR (nominally 15 dB) over complete standard waveguide bands in the 50 to 110 GHz region. Higher power noise sources offer amplified output power (ranging from 20 to 30 dB ENR) over the 50 to 110 GHz frequency range. Narrowband versions with high output power are offered for subsystem applications and special test equipment. These nominally offer 1 to 2 GHz bandwidth with excellent flatness and stable characteristics. An integral isolator is offered for improved VSWR. QuinStar can readily provide a custom-designed noise source to suit unique applications or subsystem requirements. Series QNS noise sources are ideally suited for measuring noise figure of amplifiers and receivers using the most currently available noise figure meters and eliminate the need for gas tubes. They are also well suited for calibra¬tion and built-in test functions in many sensitive receiver subsystems, radiometers and measurement instruments. • Broadband Coverage • High Noise Power Output • Compatible with Most Noise Figure Meters • Fast Rise/Fall Time
