Welcome to the first course of the RF certificate series. In this topic
we are going to explain the basic concepts of RF design in a simplest way
possible. The audience for the RF basic course are electrical engineers,
technicians, sales engineers and other employees of an RF-related company who
want to have general idea of RF basic concepts. At the end of this course
you will have a general knowledge of the fundamental topics discussed in RF
industry. This is a great crash course for people who have interviews and need to
a refresher on the RF topic within a few hours and go from zero knowledge to
having a general understanding of most topics.

One of the most important things for us to have the most updated materials
needed in the industry. Ahsan Ghoncheh, our Co-Founder and Technical
Adviser, consults with different RF engineers at Broadcomm, Qualcomm,
Apple and Skyworks on building practical curriculum and topics that are needed
and in demand  in the industry. So instead of going the academic
approach, we are going to an industry approach.

I want to thank you for choosing Rahsoft and trusting
us. Please feel free to contact us. We are truly excited and
grateful to be going with you on this journey to becoming an RF
expert. If you have any further questions, do not hesitate to contact us.

The course provides primitive knowledge for students to pursue RF Circuit Design as a course or a research. The course gives an understanding about how basic passive components change their behavior at radio frequency due to high frequency signals and fabrication using VLSI Technology in less than an hour. It makes the students understand how to approach this field with varied exercises. The course has been designed in such a way which will help students understand the concepts through exercises and not through just theoretical concepts.

Researchers all around the world are working on the performance of analog and digital circuits at Radio frequency. Satellite Broadcasting, GPS, Remote sensing are some of the applications at this frequency. The basic blocks of receiver, transmitter, mixers, LNA, filters and oscillators all are designed to work at such a high frequency.

At Radio Frequency convention circuit behavior and principles do not apply. The course is designed to be completed in less than an hour. If you want to familiarize yourself with RF industry and don't know where to start, then this is the course for you.

The Course is divided into three sections:

Radio-frequency skin tightening is an aesthetic technique that uses radio frequency energy to heat skin with the purpose of stimulating cutaneous collagen, elastin and hyaluronic acid production in order to reduce the appearance of fine lines and loose skin.

Radiofrequency skin tightening delivers heat deeply into the skin to cause tightening and lifting of the skin. The radio frequency skin tightening procedure is used for skin tightening which reduces the signs of aging skin to give you a more youthful appearance.

With medical aesthetic treatments growing in popularity Radio Frequency ensures you are able to offer your clients  innovative, non-invasive and painless treatments to tighten, tone and contour all area of the face and body.
The Benefits of Radio Frequency Treatment

Fast and effective with visible results from the first treatment. Ask your therapist about the SkinBase RF treatment today.

Lift, firm and tighten

A course of Radio Frequency (RF) treatments will help to lift, firm and tighten skin. RF stimulates the skin’s own ability to produce collagen and elastin.

Quick and painless

Radio Frequency is quick, convenient and painless. RF immediately reveals tighter, younger looking skin, all without the cost and pain of cosmetic procedures promising similar results.

The effects of radiofrequency treatments will continue to improve over the next few months as the skin produces new collagen. Results typically last for a minimum of six months, although with ongoing treatments, results are often long-lasting

Introduction to Radio Frequency (RF)

Fundamentals and Principles

Radio Frequency (RF) covers the spectrum from 3 kHz up to 300 GHz. RF work has gained a reputation of being something of a “black art”. It is a fact that, in general, RF products will need to be tuned as simulation tools and models are not accurate enough to get to first pass success without tuning. However, a lot of issues occur needlessly from sloppy work and a lack of understanding of basic principles. This means that, in general, a lot of issues can be solved before they even occur. This requires that the basic principles of RF are understood and there is rigorous attention to detail in all phases of design and test.

This course is an introduction to RF for design engineers, test engineers and product engineers or anyone else who needs to work with RF or has an interest in the field of RF. The emphasis of the course will be on the practical aspect rather than the mathematical aspect. The aim is for engineers to obtain an intuitive understanding of the concepts to allow them to apply these concepts in their work.

The internet offers a lot of resources for the RF engineer and it is not the objective of this course to supplant the internet, but to offer a guide for the engineer to know what to look for and where to find it. Engineers who take this course should leave knowing the basics of RF design and test, what to look for on the internet and where to find the relevant articles and calculators to help them during their work.
