| 20110074519 | TRANSMISSION-LINE TRANSFORMER - An example of a transmission-line transformer may include a transmission-line assembly and a balun assembly. The transmission-line assembly may include first and second conductors forming at least first and second transmission-line sections. The transmission-line assembly may provide a signal path through the first conductor and second conductor in series to a circuit ground. Balanced lines of the balun assembly may be connected to respective intermediate points on the first and second conductors between the first and second transmission-line sections. The transmission-line transformer may provide a signal path between a first end of the first conductor of the transmission-line assembly and the unbalanced line of the balun assembly. | 03-31-2011 |
| 20100301963 | BALUN WITH INTERMEDIATE CONDUCTOR - A balun comprising first and second transmission lines having a shared intermediate conductor. The first transmission line may include first and second conductors. The first conductor may have a first end for conducting an unbalanced signal relative to a circuit ground and a second end for conducting a balanced signal. The second conductor may have first and second ends proximate the respective first and second ends of the first conductor. The first end of the second conductor is open circuited. The second transmission line may include the second conductor and a third conductor having a first end connected to circuit ground and a second end for conducting the balanced signal. A resistor may connect the second end of the second conductor to circuit ground. | 12-02-2010 |
| 20090243750 | BALUN WITH SERIES-CONNECTED BALANCED-SIGNAL LINES - A balun may include series-coupled balanced-signal lines. In some examples, a balun may include a first transmission line having a first unbalanced signal port on which an unbalanced signal may exist relative to circuit ground; a second transmission line having a first balanced-signal port may be connected in series with a third transmission line having a second balanced-signal port. In some examples, a fourth transmission line may be coupled to the first transmission line and have a third balanced-signal port. A fifth transmission line may be connected in series with the fourth transmission line and have a fourth balanced-signal port. In some examples, the transmission lines may be coaxial. Balanced signals may exist between the first and second balanced-signal ports and between the third and fourth balanced-signal ports. Series-connected coaxial transmission lines may be formed of a single coaxial line with a gap in the outer conductor separating the two coaxial transmission lines. | 10-01-2009 |
