Microwave Techniques produces coaxial switches for high-power RF transfer switching and broadcast applications such as: TV, AM, FM, and UHF. One unique feature of these switches is the coplanar port configuration. In most installations, this permits neater and much more compact layouts. In addition, these layouts often require fewer elbows. For pricing, availability, and shipping time, contact our RF team today.
Coaxial RF Transfer Switches: Design Features
Microwave Techniques coaxial switches are available with a range of standard accessories and optional features. From number of ports, to options for connector types, interlocks, and control – these coaxial RF transfer switches are the de facto standard and best-in-class switches of the broadcast RF industry. An overview of their design features includes:
- Broadband
- Compact, light weight design
- Compatible with computer control
- Independent interlock/logic circuits
- Standard sizes from Type N to 6-1/8″ EIA
- Options available for 3-port and 4-port configuration
Product Description
Coaxial switches are designed primarily for application in TV, AM, FM, UHF, as well as other broadcast related areas. As four-port transfer switches they will switch two signal sources between loads. Since they can also be used as SPDT switches, complex-switching matrices can easily be assembled. A unique feature of these coaxial switches is the coplanar port configuration. In most installations, this permits neater, more compact layouts and requires fewer elbows.
These switches are usually one-half to one-third the weight and occupy between one-half and one-sixth the volume of other commercially available switches. Each switch incorporates independent interlock/logic circuits for transmitter blanking, logic input, or position indication. These circuits are isolated from the switch control circuits and from ground.
Internal interlocks are also included to remove the drive power at the end of the switching cycle to prevent inadvertent damage to the drive motor. Action is accomplished by a standard high torque gear motor and is bi-directional to positive stops. In the event of loss of control power, these coaxial switches can operate manually.
Since these switches can be controlled in groups or singly from remote locations, as well as integrated into computer controlled logic systems, they are ideally suited for use in unattended transmitter operations.
