Abstract:
1. A method comprising: receiving, at an input port, radio frequency (RF) signals; receiving, from a power supply associated with first circuitry configured to amplify the RF signals, an indication of the power supply's load level, the first circuitry including at least two low-noise amplifiers to amplify the RF signals and a variable attenuator to adjust an amount of gain by which the first circuitry amplifies the RF signals; determining, based on the indication of the power supply's load level, that the first circuitry is in a state of oscillation; directing, via two RF relays of second circuitry configured to bypass the first circuitry and in response to the first circuitry being in a state of oscillation, the RF signals received at the input port through an RF bypass circuit effective to bypass the first circuitry and enable transmission of the RF signals via an output port; adjusting, based on a predefined amplification threshold, an amount of gain by which the first circuitry amplifies the RF signals to resolve the first circuitry's state of oscillation; receiving, from the power supply, another indication of the power supply's load level; determining, based on the other indication of the load level, that the first circuitry is no longer in the state of oscillation; directing, via the two RF relays of the second circuitry and in response the first circuitry no longer being in the state of oscillation, the RF signals received at the input port to the first circuitry effective to resume amplification of the RF signals to provide the amplified RF signals; and transmitting the amplified RF signals via the output port.
