1. A PIN diode single-pole, single-throw switch, comprising:

  • an input terminal;

    an output terminal; and

    first and second transmission-line elements connected in parallel to the input and output terminals, each of the first and second transmission-line elements including;

    a thermoconductive dielectric substrate; and

    a microstrip line disposed on the thermoconductive dielectric substrate, the microstrip line including a plurality of substantially parallel sections that are magnetically coupled, electrically connected in series, and arranged so that electrical current flows in substantially the same direction in adjacent substantially parallel sections to mutually reinforce the magnetic fields associated with the adjacent substantially parallel sections;

    wherein adjacent substantially parallel sections of each of the first and second transmission lines are separated by a predetermined distance, each substantially parallel section has a predetermined width, and the predetermined distance is less than or equal to the predetermined width.
