摘要： Circuitry, which includes a package interface, a radio frequency (RF) amplification circuit, and a closed-loop gain linearization circuit. The package interface receives an RF signal and provides an amplified RF signal. The RF amplification circuit amplifies the RF signal in accordance with a gain of the RF amplification circuit so as to generate the amplified RF signal. In one embodiment, the closed-loop gain linearization circuit is configured to endogenously establish a target gain magnitude using the RF signal and linearize the gain of the RF amplification circuit in accordance with the target gain magnitude. By endogenously establishing the target gain magnitude using the RF signal, the closed-loop gain linearization circuit can provide linearity with greater independence from external control circuitry.

摘要： A multi-parallel magnetic-filed cancellation type transformer includes a plurality of coils which generate magnetic flux during energization and a core having a plurality of magnetic leg portions on which the coils are wound, and bases for fixing the magnetic leg portions. The plurality of coils are wound on the magnetic leg portions in such a manner that the magnetic flux generated from the coils are formed in the directions opposite to each other. A plurality of closed magnetic circuits of the magnetic flux are formed at the magnetic leg portions and the bases. The magnetic resistance of the closed magnetic circuits is homogeneous. Accordingly, the transformer can reduce the size thereof, and prevent the deterioration of electric power conversion efficiency.
