How RF Trends in Electronics Are Impacting Connectors

Mark Stanley

Epec Engineered Technologies

When it comes to electronics, technology is moving forward at a rapid pace and component manufacturers are trying to keep up. Devices are becoming smaller and more complex, whether it is a smartphone, medical imaging device, or a remote sensor accessing military satellite systems. At the same time, the devices still need to be rugged enough to withstand enormous amounts of wear and tear while offe...read more

5G NR (New Radio) Frequency Bands

Raghav Kapur - everything RF

Mar 12, 2018

On 21st December 2017, in Lisbon, the 3GPP TSG RAN Plenary Meeting successfully approved first implementable 5G NR specification. The completion of the first 5G NR standard enables the full-scale development of 5G NR for large-scale trials and commercial deployments as early as in 2019. This first specification was completed as part of 3GPP Release 15.As per 3GPP release 15, the frequency bands fo...read more

Feb 8, 2018

A VCXO is a Crystal Oscillator that varies output frequency based on an applied control voltage. The maximum variation in VCXO's output frequency over changes in control voltage under a constant supply voltage and temperature - specified in ppm - is called Pullability or Total Pulling Range.The Absolute Pulling Range is the minimum guaranteed deviation of the VCXO from the center frequency, when t...read more

What are the advantages of using GaN-on-Diamond technology for RF Power Amplifiers?

Amplifiers GaN

GaN-on-Diamond is the ultimate building block for an RF Power Amplifier; it gives the system designer a new thermal envelope to use for any number of product or system transformations. Through the application of GaN-on-Diamond materials, Akash’s technologies can resolve issues critical to the expansive growth of data use and consumption, enabling smaller, lighter and higher performing satellites t...read more

What is GaN-on-Diamond technology?

GaN

Gallium nitride (GaN)-on-Diamond technology is a pioneering materials invention from Akash co-founder, Felix Ejeckam that is created by lifting GaN thin films from its original growth substrate and transferring it to a synthetic CVD diamond substrate which, at 1,600-2,000 W/mK, exhibits the highest known thermal conductivity (4+ times higher than the next best materials) ever manufactured. Bringin...read more

What are Gunn Diode Oscillators?

Oscillators

The “Gunn diode” is the semiconductor used in the Gunn oscillator. The Gunn diode, also referred to as a “Transferred Electron Device,” was invented by J. B. Gunn in 1963. It is a two-terminal “negative” resistance device. Gunn oscillators have been playing a unique role in replacing the tube to generate low to medium level microwave power in the frequency range of 2 to 140 GHz. This became especi...read more

Jan 5, 2018

Noise Factor is the measure of degradation of the signal to noise ratio in a device. It is the ratio of the Signal to Noise Ratio at the input to the Signal to Noise Ratio at the output. Since the signal to noise ratio at the output will always be lower than the Signal to Noise ratio at the input, the Noise Factor is always less than 1. The Lower Noise Factors results in better performance of a de...read more

Mergers and Acquisitions in 2017

Jan 3, 2018

The year of 2017 saw a host of mergers and acquisitions taking place round the year in the RF & Microwave industry. The zeal to become global power-houses for some and the need to boost their technological supremacy for others resulted in a number of mergers and acquisitions. While Broadcom’s unsuccessful acquisition bid for Qualcomm remained the highlight of all, Keysight’s acquisition of Ixi...read more

What is a Corner Reflector?

Radars

Yonghui Shu

Sage Millimeter

The corner reflector is a passive device used to directly reflect radio waves back toward the emission source. Therefore, the corner reflector is a useful device for radar system calibration. In general, the corner reflector consists of mutually intersected perpendicular plates. The commonly seen corner reflectors are dihedral and trihedral.While the dihedral corner reflector is sensitive to its m...read more

Third order intercept point is an hypothetical point where the power of third order components will reach to the same level of fundamental component's power.If one draws the power input versus power output, they will observe the different frequency components having different slopes (fig1).So, Third order intercept point is an ideal point as once the device reaches to 1 dB compression point the tw...read more

What is a Gain Equalizer?

RF Basics

In general, RF amplifiers demonstrate a characteristic that their gain decreases with frequency as shown in Graph 1 below. Likewise, RF Cables and Passive components have a characteristic that involves insertion loss and frequency, but their insertion loss increases with frequency as shown in Graph 2 below. Those characteristics can pose significant risk when used without compensation in Satellite...read more
