1、The Industry Leader for High Frequency Components Precision RF Made in U.S.A. 11410-00235, Rev: D Data subject to change without notice Precision RF misalignment of the male pin with respect to the female contacts. To solve the problems the K Connector male pin is deliberately made shorter than the
2、SMA or 3.5 mm pin. With this arrangement, the outer housing is properly aligned prior to the mating of the center conductors. Thus a proper, non-destructive alignment before mating is ensured. The effect of pin gap on a connection is often overlooked, but is the dominant source of error in many conn
3、ection systems. Pin gap is the short length of smaller diameter caused when a connector pair is mated. Pin gap causes a discontinuity at the connector interface. The K Connector has considerably less susceptibility to pin gap than either SMA or 3.5 mm connectors. Many connector manufacturers specify
4、 connector performance assuming no pin gap, an unrealistic assumption. K Connectors are specified assuming pin gap to be at its maximum tolerance, to provide you the assurance of real-world specifications. Compatibility The K Connector interfaces electrically and mechanically with 3.5 mm connectors,
5、 including SMA and 3.5 mm without degradation in performance. Launcher design At the heart of the K Connector product line are the launchers. As their name implies, the launchers “launch” (make the transition) from a microwave circuit (microstrip, suspended substrate, stripline, or coplanar waveguid
6、e) to a coaxial connector and an outside transmission line. The key to making the transition without compromising electrical and mechanical objectives is the glass bead in the launcher assembly.

8、mm center conductor and readily connects to fragile devices. The bead is appropriate for most applications employing Duroidand ceramic (Alumina) microstrip, such as the 0.25 mm wide transmission line on a 0.25 mm thick Alumina substrate. Applications using suspended substrate geometry are equally we
9、ll satisfied. The bead is constructed of Corning 7070 glass and has a gold-plated center conductor and a gold-plated Kovarcollar. The outstanding design of the bead is largely accountable for the excellent performance of the K Connector launchers. Because the small 0.30 mm pin introduces minimal dis
10、continuity, return loss is typically better than 20 dB at 40 GHz and better than 25 dB below 18 GHz. In addition, the design provides for soldering the bead to achieve a hermetic seal. 310C max. soldering temperature is recommended. Both the sparkplug (screw-in) and the flange-mount K Connector laun
11、chers offer an additional advantage over existing designs. These launchers do not use an epoxy pin to secure the center conductor, as used in some SMA designs. Without an epoxy pin, the outer conductor remains solid, and thereby eliminates the leakage path common to pin-captivated designs. Furthermo
12、re, K launchers have a wall thickness that is four times that of typical launchers (0.8 vs. 0.2 mm). The heavier wall results in superior resistance to over- torquing. Finally, the K Connector launcher can be removed for repair without removal of the glass bead. This ensures that during removal the
13、critical microcircuit-to-glass bead interface is not disturbed, hermeticity is preserved, and the micro-circuit will not be subjected to the additional stress caused by heating to soldering temperature. Hardware locking compound such as “Removable Loctite” should be used to further secure the screw-
14、in launcher in its housing. Complete family Virtually every interface need can be satisfied by one or more of the K Connector items offered. There are six different models of K Connector launchers. Two sparkplug (screw-in) launchers are available, the K102F female version and the K102M male version.
15、 Both screw into the housing that encloses the microwave circuit, and, like all Anritsu launchers, they can be easily removed for replacement or repair without unsoldering the glass bead and its interface to the microwave circuit. When the housing that encloses the microwave circuit is not thick eno
16、ugh to support a threaded, screw-in launcher, flush-mounted (flange) launchers are required. Models with two mounting holes are available in both male and female versions, K103M and K103F. Two other models, the K104F and K104M, have four mounting holes. Mounting hole spacing is identical to that of
17、similar SMA flange launchers. The glass bead interface, of course, is the same design used for the sparkplug launcher. Cable connectors Both male and female cable connectors are available. The cable connectors, K101M and K101F, use gold-plated, beryllium- copper center conductors for optimum perform
