Abstract: A power divider includes an input port and a plurality of output ports. The power divider further includes a splitter fabricated from a plurality of discrete elements including at least one transformer having a ferrite core. The splitter has an input and a plurality of outputs. The power divider further includes a plurality of transmission lines fabricated on a printed circuit board. Each transmission line has a first end coupled to one of the outputs of the splitter and a second end coupled to one of the output ports, and includes a plurality of transmission line sections between the first end and the second end. The power divider further includes a plurality of balance resistors each having a first end connected between sections of one of the transmission lines, and having a second end connected between sections of another of the transmission lines.

Abstract: A testing device for testing transceivers includes a transmitter operable in a first state to transmit signals, a receiver operable in a second state to receive signals and a power coupler coupling the transmitter to the receiver. The testing device further includes an overload protection device operably coupled between the power coupler and the receiver to reduce or maintain the signal strength of a received signal at the receiver based on a control signal. A controller determines a current state of the received signal and generates the control signal based on the current state of the received signal.
