As introduced before, RF circulators are used in a variety of RF circuit design applications. Usually, they tend to be used at microwave frequencies, so they are often called microwave circulators. Here, we will introduce two common applications of circulators.   Duplexer: One of the most common applications for RF circulators is in radar systems or radio communication systems where the......Detail
The RF circulator has its own circuit symbol to facilitate its representation on electronic circuit diagrams or schematics. The basic symbol consists of a circle and an arrow, indicating the direction of the power cycle. Usually, the ports are shown in clockwise order around the circle: port 1, port 2, and finally port 3. If the component is done by counter-clockwise, it is marked in counte......Detail
The power divider is a device that divides the power of one input signal into two or more outputs with equal or unequal energy, and can also conversely combine the energy of multiple signals into one output, when it is called combiner.     A certain degree of isolation should be guaranteed between the output ports of a power divider. Power divider is also called over-current......Detail
In a microwave system, it is often necessary to divide the microwave power of one channel into several channels in proportion, which involves power distribution issues. The components that realize this function are called power distribution components or couplers, which mainly include: directional couplers, power dividers and various microwave branch devices.   This article mainly i......Detail
A power amplifier is an electronic amplifier designed to increase the magnitude of the power of a given input signal. It is used to increase power of input signal to operate speaker, headphone and RF transmitter electrical level of output load. Different from Current and Voltage Amplifiers, the Power Amplifier are designed to directly drive a load and serve as the final block in the amplification ......Detail
RF Circulators and Isolators are defined as RF Ferrite component, transfer RF signals by control of the ferrites. An RF signal experiences a low loss in the direction of arrow and high loss in reverse due to its non-reciprocal.   RF Circulators and Isolators non-reciprocal work on the magnetic fields. RF signal can still be reciprocal in the magnetic fields without RF Ferrite. Resonant ......Detail
