16 Way Power Divider
An RF power divider is a multi-port passive device whose core feature is to split an input RF signal into multiple output signals according to a specific ratio (typically equal amplitude and in-phase), while ensuring good isolation and impedance matching among all ports.
An RF power divider is a multi-port passive device whose core feature is to split an input RF signal into multiple output signals according to a specific ratio (typically equal amplitude and in-phase), while ensuring good isolation and impedance matching among all ports.
Its core features include:
Power Distribution/Combining: The most basic function—dividing the energy of a single input signal into two or more output paths (used as a power divider), or conversely, combining multiple signals into a single output path (used as a combiner).
Equal-amplitude in-phase output: The most commonly used Wilkinson power divider has output signals with equal amplitudes and identical phases.
High isolation between ports: The output ports are isolated from each other, meaning that impedance changes in one port will not affect the performance of other ports. This is achieved through an internal resistor network.
All port impedance matching: The input and all output ports are matched to the system’s characteristic impedance (e.g., 50Ω), ensuring efficient signal transmission and minimizing reflections.
Key parameters include insertion loss, amplitude balance, phase balance, port isolation, and return loss. These parameters are widely used in scenarios requiring signal distribution and combination, such as antenna arrays, power amplifier combining, and test systems.
