Abstract
Front-end systems for a transmitter included in a radio device are disclosed. An example front-end system may comprise a voltage-to-power mixer. The voltage-to-power mixer may be configured to up-convert a baseband signal to a high-frequency signal by multiplying the baseband signal with a local oscillator signal. Additionally, the voltage-to-power mixer may include a voltage feedback circuit. The example front-end system may further comprise a two-stage power amplifier. The two-stage power amplifier may be configured to amplify the high-frequency signal.
