RF Oscillators are an essential component to most RF signal chains, as they are used as local oscillators (LOs) with frequency conversion circuits, as a reference frequency, and in frequency synthesis/generation circuits. The basic purpose of RF Oscillators is to...
All About Calibration Kits
RF VNA Calibration Kits are essential test and measurement hardware for nearly all types of VNA measurements. Though VNAs come with internal calibration from the manufacturers, there are a variety of environmental and temporal factors that could lead to significant...
RF Frequency Synthesizers
RF Frequency Synthesizers are highly versatile RF frequency sources that are used in laboratories as test instruments to radar and signal intelligence systems as frequency sources. The key differentiation between RF frequency synthesizers and local oscillators or...
RF Power Amplifier Classes Demystified
There are a variety of classes of RF Power Amplifiers that exhibit features that may be more desirable for certain applications. The main RF power amplifier critical features of efficiency, power output, gain, and linearity are not the only key characteristics but are...
All About DC Blocks
A RF DC Block is a critical component of many RF systems where power is carried along the same paths as the RF signal. This function is essential for some devices. However, the presence of DC on a signal path is also detrimental to the performance of some DC...
RF Antennas: SISO Versus MIMO RF Antennas
There are a wide range of antenna technologies available today. A more recent option is to choose a multi-input multi-output (MIMO) antenna. Though newer, is a MIMO antenna better than a traditional single-input single-output SISO antenna? More is always better right?...
RF Balun Overview
RF Baluns, and their less common cousins, ununs, are predominately used throughout the RF & Microwave industries for impedance transformation applications, mainly impedance matching. Baluns, specifically, match impedances between balanced and unbalanced circuits....
Whitepaper: Where COTS Meets Hi-Rel for RF/Microwave Active Devices
The process of designing and producing high reliability (Hi-Rel) military/aerospace (Mil/Aero) and space-grade RF and microwave active devices has historically been a long and expensive endeavor focused on small or medium quantity manufacturing. Adding to this, the...
What is an RF Detector?
RF Detectors, or RF Signal Detectors, are simply devices that are able to give some type of indication that RF energy has somehow been coupled into the device. There are a wide variety of RF detector implementations, as well as thousands of knock-off “bug...
All About Waveguide to Coaxial Adapters
Outside of board-level RF interconnect, waveguides and coaxial interconnect are the most common types of RF interconnect. Waveguides are typically used with higher power, higher fidelity, and higher frequency banded applications. Coaxial transmission line interconnect...
