Knowledge of RF Circulators
RF or microwave circulators or isolators are devices that typically have three and sometimes four ports, and they are used in RF system designs that need to transmit power from one port to another while isolating the power from the other port.
RF Isolators
Microstrip Isolators are RF Isolators that are built using microstrip technology. These circuits are designed using microstrip transmission lines and can be used for high frequency commercial, space and military applications. When identifying microstrip isolators, you need to specify the frequency range of operation in which you plan to use the device, the power that you need the isolators to handle, the insertion loss that you system needs and the port to port isolation that you need.

More about RF Terminations and RF Loads
RF Terminations or loads absorb incident power at a port with minimal reflection, minimizing signal reflection back into the circuit or system. This is done by terminating the port in its characteristic impedance. Any multi-port RF system, whose ports are not all being used should be terminated so that there are any signal incident on these ports will be absorbed.
RF Attenuator Basics & Selection
More about RF Variable Attenuators
Variable attenuators, like the name suggests, are attenuators whose attenuation amplitude can be changed by varying the voltage/current or turning a knob, toggling a switch or through a computer. These attenuators are used in applications where it is required to vary the amplitude of the signal level.
More about RF Resistors
What is RF Resistors? Simply put, the resistor used in radio frequency microwave communication system is called radio frequency resistor. Everyone should be clear about the radio frequency current, which is a short form of high frequency alternating current electromagnetic wave.
How to Select a RF Power Divider
RF Power Dividers are passive RF devices that split an input signal into two or more output signals with minimal losses. Power dividers are widely used in wireless systems to divide power across equally across the system.
Technical Notes of Feedthrough Capacitors
A number of different electrical configurations are available in EMI filters, including the common types shown opposite. A single element filter (a capacitor or an inductor) theoretically provides an insertion loss characteristic of 20dB per decade, a dual element filter (capacitor and inductor) 40dB per decade whilst a triple element filter(Pi or T configuration) theoretically yields 60dB per decade.
