CW Power Capacity vs Frequency (Electromechanical Switches) By: Canaan McGee 10/06/202 RF Electromechanical Relay Switches, RF electromechanical switches, or RF electromechanical relays are a type of RF switch with mechanical contacts driven by electrically driven actuators. The transmission paths within an Electromechanical relay switch are purely passive, and thus exhibit relatively low loss and high isolation compared to...

VSWR, Return Loss, Insertion/Transmission loss vs. Transmission Power By: Steve Bowman In an ideal RF system, all of the energy from the RF source is transferred to the load. An example of this would be a transmitter delivering a signal to an antenna with the interconnect between the two signal chain components operating at 100%...

Why Hermetically Seal RF Adapters and how is it done? RF coaxial adapters are often the difference between expensive options of reordering RF cable assemblies, RF connectors, or even retrofitting RF assemblies with new RF coaxial connectors, and a few seconds of installing a quick fix. Also, RF adapters are useful in protecting/extending the life of the RF...

The Wide and Diverse World of RF Antennas 900 MHz Patch Antenna Electromagnetic (EM) Antennas are an essential component for virtually all transmission and reception systems that operate in the RF, microwave, millimeter-wave (mmW), and terahertz (THz) frequency ranges. Another way to look at EM Antennas, is that these antennas can be designed to convert conducted EM...

Low-PIM, Low-loss, and Phase-Stable Cable Assembly Application Considerations Coaxial cables are arguably the most common RF/microwave physical interconnect technology. Outside of waveguides and planar interconnect, coaxial cable assemblies are one of the few proven methods of reliably connecting RF/microwave/millimeter-wave networks. Given the diverse range of applications for coaxial cable assemblies, these cables are not one-size-fits-all. There are a...

Bidirectional Amplifier Basics By: Steve Bowman 06/23/2022 A Bidirectional Amplifier, or Bi-directional Amplifier (bda), is an active RF device that is widely used in a variety of telecommunication, radar, and other RF sensing applications. Though conceptually a Bidirectional Amplifier performs a relatively simple operation, the internal electronics can be somewhat complex. Moreover, many applications favor certain names and types...
