Radio frequency transceiver front-end systems and methods

Systems and methods for improving operational efficiency of a radio frequency system, which includes a low noise amplifier coupled to an antenna that generates an analog electrical signal based on received electromagnetic waves. The low noise amplifier includes a positive input transistor with a first drain, a negative input transistor with a second drain, a first data branch coupled between the first and second drains, and a second data branch coupled between the first drain and second drains. The first data branch supplies a first current modulated signal generated based on the analog electrical signal when the radio frequency system expects the received electromagnetic waves to include data indicated using a first communication protocol. The second data branch supplies a second current modulated signal generated based on the analog electrical signal when the radio frequency system expects the received electromagnetic waves to include data indicated using a second communication protocol.
