摘要:
A high power RF or microwave amplifier may amplify an RF or microwave input signal. The high power RF or microwave amplifier may include an input signal divider (DIV) that has an input port that receives the RF or microwave input signal and that divides this input signal into multiple sub-input signals; multiple power amplifier units (PAUs), each having an input port that receives an RF or microwave signal, an output port that delivers an amplified version of the received RF or microwave signal, and an interface port; an interface control unit (ICU) that communicates with each PAU through its interface port; and an output signal switching combiner unit (SCU) that coherently sums the outputs of the on-line PAUs and delivers this to an output port. The ICU may set one or more of the PAUs to amplify one of the multiple sub-input signals (hereinafter referred to as on-line PAU in on-line mode); monitor each on-line PAU to verify that it is operating within one or more pre-determined PAU specifications; and upon detecting that one of the on-line PAUs is no longer operating within the one or more pre-determined PAU specifications (malfunctioning PAU), set the malfunctioning PAU not to amplify one of the multiple sub-input signals and not to be available to be switched to the on-line mode by the ICU (hereinafter referred to as off-line PAU in off-line mode).
摘要:
A switching combiner unit (SCU) may combine coherent RF or microwave outputs from multiple power amplifier units (PAUs). Each SCU may be able to be switched between an on-line mode (on-line PAU), during which the PAU amplifies a coherent instance of the same RF or microwave input signal and delivers that amplified input signal to an output, and a standby or off-line mode (standby/off-line PAU), during which the PAU does not amplify an instance of the same RF or microwave input signal or deliver an amplified input signal to the output. The SCU may include an input port that connects to each of the PAU outputs; a control signal input that receives one or more control signals that indicate whether each PAU is in the on-line or standby/off-line mode; signal combining circuitry that coherently sums the outputs from all of the on-line PAUs, while simultaneously isolating the standby/off-line PAUs from the output of the SCU and the outputs of the on-line PAUs; and an SCU output port that delivers the coherently summed outputs from all of the on-line PAUs.

A high power amplifier may amplify an RF or microwave input signal. The amplifier may include: an input signal divider (DIV) that has an input port for the input signal and that divides this input signal into multiple sub-input signals; multiple power amplifier units (PAUs), each having an input port for receiving one of the sub-input signals and an output port for delivering an amplified version of the received signal; multiple power supply units (PSUs), each connected to power a different one of the PAUs; and an interface control unit (ICU). The ICU may: monitor each PSU to verify that it is operating within one or more pre-determined PSU specifications; and upon detecting that a PSU is no longer operating within the one or more pre-determined PSU specification (malfunctioning PSU), set the PAU being powered by the malfunctioning PSU (online PAU in online mode) not to amplify one of the sub-input signals and not to be available for being switched to the online mode (offline mode of offline PAU).
摘要:
A power divider may coherently divide an RF or microwave input signal into multiple instances of that signal. The power divider may include: an input port that receives the input signal; multiple output ports; and passive signal splitting circuitry that causes a different instance of the input signal to be delivered to each of the output ports all substantially in phase with one another and with substantially equal amplitude, but isolates any signal that is reflected back to one of the output ports from a device to which the output port is connected from any of the other output ports.

A cableless high power RF or microwave amplifier may amplifies an RF or microwave signal. The amplifier may include: an input signal divider (DIV) that has a DIV input connector that receives the RF or microwave signal and that divides this input signal into multiple sub-input signals, each of which is delivered to a DIV output connector; multiple power amplifier units (PAUs), each of which has a PAU input connector that receives an RF or microwave signal and a PAU output connector that delivers an amplified version of the received RF or microwave signal; and an output signal switching combiner unit (SCU) that has multiple SCU input connectors and that coherently sums the signals at the multiple SCU input connectors and delivers this to an SCU output connector. Each of the PAU output connectors may be electrically connected to a different one of the SCU input connectors without connecting cables.
