Abstract
The embodiments described herein use resonant circuits to provide isolation between closely proximate conductors. For example, these resonant circuits can be used to reduce unwanted electromagnetic coupling and minimize crosstalk energy between package leads, bonding wires, and circuit board traces on radio frequency (RF) electronic devices, including RF power amplifiers. To facilitate a reduction in electromagnetic coupling, the resonant circuit is configured resonate with the closely proximate conductors at a selected frequency f0, and when resonating at the selected frequency f0 the resonant circuit provides a path to ground for the crosstalk energy. This path to ground reduces the crosstalk energy that would otherwise be shared between the two closely proximate conductors, and thus provides the electromagnetic isolation between the conductors.
