Dow-Key Microwave Corporation is the world’s largest RF and Microwave switch manufacturer offer an extensive line of electro-mechanical coaxial switches. Coaxial switch is an electromechanical relay ‐ a passive component ‐ used to direct RF signals from one path to another path. This type of switch is widely used in signal routing applications where high frequency, high power, and great RF performances are required.
Coaxial Switches Special Options
Dow‐Key coaxial switches are offered with many options to meet any type of specification and to fit most application.
Extended Temperature: This option extends the standard operating temperature from ‐25ºC to
+65 ºC to ‐25 ºC to +85 ºC.
Epoxy Seal: It extends the standard non‐condensing humidly rating from 90% to 95%.
Immersion Seal: It extends the non‐condensing humidly rating from 90% to 100% (water proof).
D‐sub Connector: Instead of standard terminal pins, a d‐sub connector (9‐pin, 15‐pin, or 25‐pin) is available depending on the switch series.
Power Connector: Instead of standard terminal pins, a circular plug is available.
Reverse Polarity: Instead of +Vdc and –COM coil voltage terminals, the reverse polarity –Vdc and +COM is available.
26.5 GHz: Extends the standard DC‐18 GHz bandwidth to DC‐26.5 GHz. This option is only
available for some series.
40 GHz: Extends the standard DC‐18 GHz bandwidth to DC‐40 GHz. This option is only available for some series.
Flange Mount: Radial switches are not offered with mounting holes. This feature can be available by adding a flange.
Mounting Bracket: If mounting holes required other than the ones available on a flange, this option is offered as an alternative.
Bypass: This options applies to transfer DPDT switches only. One can select to bypass a specific path: J1‐J2, J2‐J4, J3‐J4, or J1‐J3.
Low PIM: Extends the standard ‐110 dBc PIM level to ‐160 dBc. This option is available for most switches.
