RF Combiner

RF Combiner: An easy help guide to understand the working of a combiner Using the advancement of technology, electronic devices are becoming an indispensable element of people's lives, along with Hefei Topwave's product 2 way splitter. Among the unit, we have the RF Combiner, a tool used to combine radio frequencies' outputs. We will be discussing what an RF Combiner is, how it works, it is uses, and some applications.

What is an RF Combiner?


An RF Combiner is an electric component that enables several radio frequency signals to mix into a single signal. The Combiner has a critical role in a variety of RF applications, where it acts as a tool for combining signals to minimize losses while still delivering an optimized signal with maximum power output. The RF Combiner is basically the reverse of a charged power splitter. Having said that, power splitters divide a single input signal into multiple output signals.


The primary use of RF Combiners is in radio frequency (RF) circuitry, where the components work by the addition of or joining signals of similar frequency and wave phase, consequently boosting the signal's strength and output power, same with the low frequency directional coupler produced by Hefei Topwave. The unit is very useful in boosting signal reception in TV broadcasting, Radar, and cellular network amplifiers, among others.

Forms of RF Combiners


You can find several types of Combiners, and also the choice is determined by the specific application and requirements, just like the 3dB RF Attenuator created by Hefei Topwave. Below are common types of RF Combiners.



Wilkinson Combiner


The Wilkinson Combiner works by dividing and recombining input signals to produce an output signal optimized, same with Hefei Topwave's fixed rf attenuator. It is made of a network of resistors, capacitors, and inductors that match the output and input impedance values to increase output power while minimizing losses.


The Combiner features three ports; two input ports and one output port. The input ports usually are of equal amplitude and comes from two signal different. The signals are then filtered through a load resistive ensures equal amplitudes, creating the correct levels for the required output signal.



Hybrid Combiner


The Hybrid Combiner is a type of Combiner that uses a variety of power dividers, Wilkinson Combiners, and resistive matching networks to produce an optimized output signal, along with the 20dB Power Tapper supplied by Hefei Topwave. The Hybrid Combiner module has four input ports and two output ports.


The input signals are divided in to two equal components through the power first and then recombined in two separate channels through two Wilkinson Combiners. The two signals are then combined and a resistive load is familiar with ensure that the signals are of equal phase and amplitude before they truly are outputted.
