Millimeter-Wave Technology & DesignMODEL PRODUCT NAME PERFORMANCE/CAPABILITY SUMMARYCGC Crossguide Coupler The series CGC compact crossguide directional couplers areoffered in the frequency range of 18 to 170 GHz. The nominalcoupling value is 20 dB. Directivity ranges from 17 dB at the lowerend of the band to 12 dB at the high end for all three-port unitsbelow 110 GHz. For complete coverage of each waveguide, eachmodel (low, mid or high) provides nominal performance over thewhole band, but meets the full specifications only over the specificportion of the waveguide band. These couplers are offered with thefourth port either internally terminated or unterminated (accessible).CL33-Port High DirectivityDirectional CouplerThe series CL3 high directivity coupler covers 18 to 170 GHz in ninewaveguide bands. The coupler is offered with coupling values of 3,6, 10, 20, 30 or 40 dB, and covers a full waveguide band. It hasdirectivity of 37 dB up to 60 GHz and drops to 28 dB up to 170 GHz.CMT Magic Tee Hybrid Coupler The series CMT magic tee hybrid coupler covers 18 to 170 GHz innine waveguide bands. Each coupler is offered in two versions, oneproviding a bandwidth of 60% and the other providing a bandwidthof 90%.CSS Short Slot Hybrid Coupler The series CSS short slot hybrid coupler covers 26.5 to 170 GHz innine waveguide bands. The two output ports are in-line to the inputport, and have 90° phase difference with nearly equal power levelsover 5% of the center frequency. Isolation between output ports is20 dB (typical).FXAPassive Waveguide ProductsGeneral Purpose andPrecision Fixed AttenuatorThe series FXA general purpose fixed attenuator consists of awaveguide section with a precisely cut resistive vane. It is availablein nine waveguide bands from 18 to 170 GHz. The precision fixedattenuators are made using a rugged split block design. Thisattenuator can be used as a laboratory standard against which otherinstruments or components are calibrated.LSA Level Set Attenuator The series LSA level set attenuator consists of a waveguide sectionwith a precisely cut resistive vane. The attenuator is available innine waveguide bands from 18 to 170 GHz.VPS Variable Phase Shifter The series VPS variable phase shifter consists of a waveguidesection with a movable dielectric vane driven by a micrometer. Thisarrangement provides a phase shift range of 180.WTR Termination The series WTR termination covers 18 to 220 GHz in 10 waveguidebands. The termination consists of tapered absorbers within thewaveguide section. This termination is designed to provide amaximum VSWR ranging from 1.03:1 in WR-42 to 1.5:1 in WR-05.TLD Tunable Load The series TLD tunable load covers 26.5 to 170 GHz in eightwaveguide bands. The tunable load consists of a metric micrometertuning mechanism that allows the microwave absorber to bepositioned within the guide while maintaining a constant magnitudeof reflection coefficient. This tunable load is designed to provide atypical VSWR ranging from 1.05:1 in WR-28 to 1.1:1 in WR-06.TSC Tunable Short The series TSC tunable short covers 26.5 to 170 GHz in eightwaveguide bands. The short consists of a movable non-contactingchoke plunger within a waveguide section. The series TSC providesVSWR in excess of 20:1 in WR-28 and 15:1 in WR-06.WCA Waveguide to Coax Adapter The series waveguide to coax adapters, cover up to 110 GHz.Waveguide to coax include 2.92, 2.44, 1.85, and 1.0 mmconnectors.35Millitech, Inc. •Tel: (413) 582-9620 • Fax: (413) 582-9622 • Email: info@millitech.com
