ABSTRACT:
A method and apparatus for multiplexing broad band high frequency signals comprises a microwave coupler. A first source of signals is connected to the through-arm of the coupler and a second source of signals of higher frequency is connected to the coupling arm of the coupler. By using a coupler designed for operation at the frequencies of the signals from the second source, the loss of signal strength from the second source is significantly reduced while the loss of signal strength from the first source is only slightly greater than that incurred in prior known multiplexer.
