Suspension and drive system for a mechanical RF energy power divider intended for spacecraft applications
First Claim
1. A suspension and drive system for a variable microwave power divider including a first orthomode transducer means, a second orthomode transducer means spaced from the first transducer means and rotated a predetermined angular amount therefrom, a hollow circular waveguide means coupling the first and second transducer means, means to inject and extract RF energy into and from each transducer means, septum means positioned within the waveguide means and variable to a predetermined configuration to control the polarization of RF energy flowing through the waveguide means from one transducer means to another, and variable control rod means extending longitudinally through the power divider for controlling the configuration of the septum means, said system comprising:
- torsion spring means connecting each end of the control rod means to fixed surfaces,selectively energizeable friction brake means surrounding at least a portion of the control rod means for holding the control rod means in a predetermined angular position, andelectric motor means coupled to the control rod means and operable to rotate the control rod means a predetermined angular amount.

Abstract
A suspension and drive system for a mechanical microwave power divider for spacecraft applications. The mechanical power divider includes a control which extends longitudinally therethrough. Torsion springs connect each end of the control rod to fixed surfaces and an electromagnetic control is coupled to the control rod to rotate it to a predetermined angular position. A selectively energizeable friction brake surrounds at least a portion of the control rod for holding it in a predetermined angular position.
