ABSTRACT:
A programmable combiner including a first terminal providing a radio frequency input signal, a second terminal providing a radio frequency output signal, a plurality of linear amplifiers in connection therebetween, and switch means coupling individual ones of the plurality of amplifiers in series connection between the first and second terminals in providing a redundancy of continuing circuit operation upon the failure of any one or more amplifiers, and in providing a controllable level of output signal at the second terminal as gain characteristics of one or more of the amplifiers vary, or as different output power signal levels are required.
