Power combining for high power amplifiers

A radiofrequency (RF) power amplifier, comprising:

• a radial power divider configured to process a received RF input signal and divide the received RF input signal into at least two divided RF signals;
• an amplifier stage coupled to the at least two divided RF signals to amplify the at least two divided RF signals to a higher power level;
• a radial power combiner to combine amplified divided RF signals at the higher power level into an RF output signal;
• wherein each of the radial power combiner and radial power divider comprises:
• a circuit board having a first conductive surface forming an RF ground plane and a second conductive surface opposite to the first conductive surface;
• a communication cable operably engaged with the circuit board;
• at least two transmission lines formed on the second conductive surface of the circuit board and operably engaged with the communication cable;
• and
• at least two connectors operably engaged with the at least two transmission lines and operably engaged with the second conductive surface of the circuit board.

A method, comprising:

• receiving a first radio frequency (RF) signal from a RF detection device, wherein the RF detection device is operably engaged with a first RF apparatus;
• effecting the first RF signal to be sent, via a communication cable of the first RF apparatus, to a circuit board of the first RF apparatus, wherein the circuit board includes a first conductive surface forming an RF ground plane and a second conductive surface opposite to the first conductive surface;
• and
• dividing the first RF signal into at least two RF signals, via at least two transmission lines of the first RF apparatus, to at least two RF connectors of the first RF apparatus, wherein the at least two transmission lines are formed on the second conductive surface of the circuit board and operably engage with the communication cable;
• and wherein the at least two RF connectors operably engage with the second conductive surface.
