ABSTRACT:
A common input junction, multioctave, printed microwave multiplexer. In a first preferred embodiment the multiplexer is in the form of a microstrip. In an alternative preferred embodiment the multiplexer is provided in the form of a suspended substrate multiplexer. Each of the preferred embodiments include independently formed first, second and third channels each having an input and an output, with the input of each channel being coupled together and to a common input junction. The channels are adapted to simultaneously receive radio frequency (RF) signals in the range of, for example, about 3 to 18 GHz. The first independent channel provides an RF output signal having a frequency range of preferably about 3 to 5.5. GHz. The second independent channel provides an RF output signal having a frequency range of about 5.5 to 10 GHz, and the third independent channel provides an RF output signal having a frequency range of about 10 to 18 GHz. The multiplexer is significantly smaller in size and weight than conventional combline and suspended substrate multiplexers, provides significantly fewer component parts, and requires no calibration adjustments.
