Abstract

A bond wire circuit includes at least three bond wires arranged to split an input signal into two output signals. In connection with various example embodiments, bond wires are arranged in a generally parallel manner to mitigate magnetic coupling and related issues for splitting an input signal and providing each of split signals to an amplifier. The bond wires are connected by capacitive circuits that facilitate the splitting, and in some applications, additional capacitive (to ground / reference) and load circuits to further facilitate the splitting of the input signals for specific amplifier circuit implementations, and applications to various loads. In some implementations, the input signals are split in equal or arbitrary portions with frequency independent phase differences in a wide frequency band, with isolation between ports of the circuit.

Description

technical field [0001] The invention relates to the field of circuits, in particular to an inductance circuit device. Background technique [0002] Various input circuits suffer from undesirable characteristics, particularly with respect to compact size and efficiency, and with respect to particular applications requiring or benefiting from input isolation. These input circuits can be used to provide inputs to various components such as amplifiers used in radio frequency circuits. [0003] Amplifiers for a variety of applications have increased dramatically, including high power MMIC amplifiers such as those used in mobile communication base stations. For these amplifiers, high power efficiency and small size are required, however these aspects are difficult to achieve. In general, higher power amplifiers are larger, and reducing component size can limit power capabilities. Furthermore, the high power devices used in these amplifiers typically must exhibit very high power...
