Abstract
A circuit for an output divider has an input port, an output port coupled to the input port at a first node, and a voltage controlled element, such as a varactor, having a first end coupled at the first node to the input port. A second end is coupled to a resistive element, such as a resistor, with the resistive element being coupled to a signal ground. The first end of the voltage controlled element is adapted to be coupled to a reference voltage of a load, the voltage controlled element having a high impedance when the reference voltage is present and having a low impedance when the reference voltage is not present. The impedance seen from the input port is substantially the impedance of the load when the reference voltage is present, and the impedance seen from the input port is substantially the impedance of the resistive element when the reference voltage is not present.
