ABSTRACT:
A three way oscillator signal power splitting circuit splits power provided at the output of a voltage controlled oscillator (VCO). The circuit is implemented on a printed circuit board section having a first layer which includes a first conductor for receiving the power from the VCO, a second layer having a second conductor, substantially parallel to and adjacent the first conductor, for receiving a portion of the power on the first main conductor via broadside coupling, and a third conductor, situated substantially parallel to and adjacent the first and second conductors, for receiving a portion of the power on the first main conductor also via broadside coupling. A ground conductor is additionally included on the third layer for providing a ground reference for the first, second and third conductors, and resistors are used to terminate the second and third conductors.
