What is Amplitude and Phase Balance in a Power Divider?

Mar 29, 2018

Amplitude balance is a measure of how evenly the power is split between the outputs of an n-way power divider. For example, in a 2 way power divider, the input signal is split into two equal output signals, however there cab be slight variations in the amplitude of each signal - this variation is called amplitude balance. It is represented in dB.Phase balance is a measure of the differential phase...read more

What is a Wilkinson Power Divider?

Wilkinson power dividers are usually realized as microstrip or stripline designs. Let’s consider a simple 2-way Wilkinson power divider. Being a lossless reciprocal three-port network, the device inherits the properties that the ports are not simultaneously matched. By placing a resistor between the two output ports high isolation between the output ports is achieved while maintaining a matc...read more
