    摘要: A bond-wire transformer (200) for an RF device is described. The primary and secondary circuits of the bond-wire transformer are formed using loops formed with a pair of normal profile and low profile bond-wires. This results in improved efficiency and higher power operation.

    摘要: A die is described comprising at least one 3-way Doherty amplifier (100) comprising a main stage (120), a first peak stage (130) and a second peak stage(140). An input network (110) includes a first impedance connected to an input of the first peak stage (130) and providing a -90° phase shift and a second impedance connected to an input of the second peak stage (140) and providing a 90° phase shift. An output network (150) includes a third impedance connected to the output of the first peak stage (130) and providing a 180° phase shift and a fourth impedance connected to the output of the main stage (120) and providing a 90° phase shift.
