Basic Building Blocks of an RF System • RF-IC Transmitter Receiver Transceiver System-on-Chip (SoC); typically transceiver with integrated microcontroller • Crystal Reference frequency for the LO and the carrier frequency • Balun Balanced to unbalanced Converts a differential signal to a single-ended signal or vice versa • Matching ...
Fixed attenuators are widely used in RF electronics to set the proper signal level in the various circuit branches. Proper level setting is crucial to fully exploit the instrumentation dynamic range and to avoid circuit overload and damaging.

RF stands for Radio Frequency, but it often used in the sense of “ anything related with EM signals”. The sine wave is the basic example of a signal that can be generated, transmitted and received with RF equipment. Frequency: the number of times a signal goes through a complete “up and down” cycle in one second of time. It is measured in Hertz.
RF Behaviour • Absorption – Conversion of the RF signal energy into heat – Happens because the molecules in the medium through which the RF is passing cannot move fast enough to keep-up with the energy oscillations in the wave – Water (and everything that contains water), drywall, wood and human bodies absorb RF waves 22 Absorption
We created this document to explain the basics of RF signals, help you understand the time and frequency domains, and introduce common RF measurement instrumentation and measurement techniques. We hope you find this information helpful. Events are …
RF Basics 01 - How do RF systems work? How RF gets audio signal from A to B? All radio frequency (RF) systems have a transmitter (TX) and receiver (RX). Transmitters and receivers can take many forms including handheld, beltpack, rack mount or desktop.
Sections of RF circuit are defined by pairs of terminals forming a port. The condition for a pair of terminals to constitute a port is that the current entering one equals the current leaving the other in both phase and amplitude.
chapter introduces you to the minimum vocabulary and concepts you will need to learn RF. Before you learned to read and write, you needed to learn your ABCs. This chapter is the ABCs of RF. In it you will be reintro-duced to terms you probably learned back in …
