The present invention relates to a programmable microwave circuit (1) four ports (3), and combinations of such circuits. Between each pair of ports there is at least one connection without amplification, at least one connection having amplification from a first port of the pair of ports to a second port of the pair of ports, and at least one connection having amplification from the second port to the first port. Further, there is control electronics (2) with the ability to open and close the respective connection and respective port, by which the microwave circuit could be configured for different purposes, such as amplifier, power splitter/power combiner and router.
