What is an Electromechanical Relay (EMR), Switch, or Relay Switch?
Within RF circuits, there is often the need to open or close one or more circuits based on timing or other triggers. In some cases, this is a single circuit at a time, in others it is many circuits simultaneously. There are now a wide variety of RF switch types, including solid state switches, microelectromechanical (MEMS) switches, diode switches, manual switches, and the venerable...
What is a Quad Ridge Dual Polarized Broad Band Gain Horn Antenna?
Waveguides are the backbone of many RF interconnects, especially when high power and high efficiency are required. Unlike coaxial interconnect, waveguides have both a minimum and maximum cutoff frequency. The single mode waveguide bandwidth is typically claimed as the bandwidth for a waveguide and the frequency difference between the lower TE10 mode cutoff and upper TE10 mode cutoff. One method...
