VITA 67, is a VPX standard for blindmate coaxial connectors that is designed for use in the backplane and plug-in modules for VPX interfaces. These interfaces allow for RF connectivity enhancements to existing VITA 46 VPX board-to-board connections. This interconnect...
Hermetic and the concept of hermiticity in RF components and devices is derived from the Greek for impenetrable barrier, and air/water tightness. This is a critical feature of many military/defense, industrial, and aerospace systems that are exposed to harsh...
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,...
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...
In modern digital communications and radar the success of communications and sensing has become extremely sensitive to phase noise as well as amplitude noise. Phase noise is the frequency domain description for jitter, which is a major component of bit-error rate...
There are many cases in RF circuit design where there is a need to increase the power of a signal while avoiding adding any signal degrading characteristics. An example of this is when a mixer needs to be driven at a certain input power beyond what is available from...
Voltage Controlled Oscillators (VCOs) are essential elements in a wide range of applications that require frequency variation based controllable signals. Examples of this include phase locked loops (PLLs), frequency modulators, radar, and frequency hopping remote...
Phase-locked-loops (PLLs) are important components in many radio communication links and test equipment that rely on quality internal signals. PLLs are used in local oscillator (LO) circuits and RF Frequency Synthesizers that are designed to maintain precision...
Radio Frequency (RF) signals are merely any useful electromagnetic radiation within a portion of the spectrum that is compatible with available technology. These can be RF signals used for communication, sensing, or any other purpose, such as RF heating, RF plasma, or...
The N-type coaxial connector (N-female connector) is one of the oldest standardized coax connectors and has been around since the 1940s. The N-type coaxial connector is one of the most commonly used RFconnector types with a typical frequency range from DC to 11 GHz,...
