RF Microwave Cavity Duplexer&Diplexer
RF microwave duplexer is a three port device used to send and receive RF signals using the same antenna in communication systems. The duplexer works as a circulator for low-power applications. In wireless devices such as smart phones and wireless LANs, the duplexer used ...Read more -
What is an RF filter and why is it so important?
What is an RF filter and why is it so important? Filters are necessary to filter unwanted signals entering the radio spectrum. They are used in combination with various electronic devices. However, its most important use is in the RF domain. ...Read more -
Wilkinson Power Divider
Wilkinson power divider is a power divider circuit. When all ports are matched, it can realize isolation between two output ports. Although Wilkinson power divider can be designed to realize any power division (for example, see Pozar [1]), this example will study the cas...Read more -
Learn About Passive Components in RF Circuits
Passive Components in RF Circuits Resistors, capacitors, Antennas. . . . Learn about passive components used in RF systems. RF systems are not fundamentally different from other types of electric circuits. The same laws of physics apply, and consequently the basic comp...Read more -
Multiplexer vs Power Divider
Both Multiplexers and Power Dividers are helpful devices to expand the number of antennas that can be connected to one reader’s port. One of the main benefits is to reduce the cost of a UHF RFID application by sharing expensive hardware. In this blog post, we explain the...Read more -
Passive RF Combiner/Multiplexer

Learn About Band Pass Filter
Passive Band Pass Filters Passive Band Pass Filters can be made by connecting together a low pass filter with a high pass filter The Passive Band Pass Filter can be used to isolate or filter out certain frequencies that lie within a particular band or range of frequenci...Read more -
Learn About Directional Coupler
Directional couplers are an important type of signal processing device. Their basic function is to sample RF signals at a predetermined degree of coupling, with high isolation between the signal ports and the sampled ports — which supports analysis, measurement and proc...Read more -
Learn About Band Stop Filter
The Band Stop Filter, (BSF) is another type of frequency selective circuit that functions in exactly the opposite way to the Band Pass Filter we looked at before. The band stop filter, also known as a band reject filter, passes all frequencies with the exception of thos...Read more
