Power amplification system is disclosed. A power amplification system can include a Class-E push-pull amplifier including a transformer balun. The power amplification can further include a reactance compensation circuit coupled to the transformer balun. In some embodiments, the reactance compensation circuit is configured to reduce variation over frequency of a fundamental load impedance of the power amplification system.

Power amplification system with reactance compensation

In some embodiments, a power amplification system can include a common base amplifier configured to amplify an input signal received at an input node to generate an intermediate signal at an intermediate node. The power amplification system can further include a power amplifier configured to amplify the intermediate signal received at the intermediate node to generate an output signal at an output node.

Common base pre-amplifier

Power amplification system with common base pre-amplifier. A power amplification system can include a common base amplifier configured to amplify an input radio-frequency (RF) signal received at an input node to generate an intermediate RF signal at an intermediate node. The power amplification system can further include a power amplifier configured to amplify the intermediate RF signal received at the intermediate node to generate an output RF signal at an output node.
