Abstract:
1. A transmission-line transformer comprising: a transmission-line assembly including first and second conductors forming at least first and second transmission-line sections, the first conductor having first and second ends and the second conductor having first and second ends, the second end of the first conductor being connected to the first end of the second conductor, and the second end of the second conductor being connected to a circuit ground, the transmission-line assembly forming a signal path between the first end of the first conductor and the circuit ground at the second end of the second conductor; and a balun assembly having first and second balanced lines and an unbalanced line, the first balanced line being connected to an intermediate point on the first conductor between the first and second transmission-line sections and the second balanced line being connected to an intermediate point on the second conductor between the first and second transmission-line sections; the transmission-line transformer providing a signal path between the first end of the first conductor of the transmission-line assembly and the unbalanced line of the balun assembly.
