摘要:
This disclosure relates generally to radio frequency (RF) amplification devices and methods of operating the same. In one embodiment, an RF amplification device includes an RF amplification circuit and a stabilizing transformer network. The RF amplification circuit defines an RF signal path and is configured to amplify an RF signal propagating in the RF signal path. The stabilizing transformer network is operably associated with the RF signal path defined by the RF amplification circuit. Furthermore, the stabilizing transformer network is configured to reduce parasitic coupling along the RF signal path of the RF amplification circuit as the RF signal propagates in the RF signal path. In this manner, the stabilizing transformer network allows for inexpensive components to be used to reduce parasitic coupling while allowing for smaller distances along the RF signal path.
