ABSTRACT:
A switch designs having very low insertion loss, in which the insertion loss remains the same regardless of the number of inputs. A plurality of inputs are structured for receiving electromagnetic radiation signal having a wavelength λ. A plurality of switches, e.g., PIN diode switches, are coupled to a respective input. A main conductor is coupled to an output. A plurality of leg conductors are coupled at one end to the main conductor and at other end to a respective switch from the plurality of switches, wherein each of the leg conductors has a length substantially equal to nλ/2, wherein n is a whole natural number.
