128-Way Power Dividers/Combiners

1. Based on Transmission Line Theory: It utilizes transmission line structures like microstrip lines or striplines. Similar to other power dividers with fewer ports, it designs appropriate impedance matching networks within the circuit. For example, by carefully choosing the characteristic impedance values of different sections of the transmission lines to ensure that the power can be smoothly divided and transmitted to each output port.
2. Ensuring Isolation: Incorporates isolation components or techniques to reduce the crosstalk between the 128 output ports so that each port can receive the divided power relatively independently and stably. For instance, using resistors or other isolation structures at key positions in the circuit layout to improve the isolation performance.
