Wireless Digital Signals Course: Online

The process of coding information onto an RF carrier is a key aspect that enables modern wireless transmission. An RF/wireless engineer needs to understand how information can be represented as changes to the properties of a carrier, as well as the impediments that the carrier faces going from the transmit antenna to the receive antenna. Although the topic is complex, many key concepts are remarkably simple to understand and help to demystify assumptions concerning frequency, range, and bandwidth requirements for example. Furthermore, understanding the basic modulation types serves as a foundation for understanding how today's elaborate commercial standards work, by seeing them as the combination of familiar building blocks alongside other more advanced techniques.

RF/Microwave EDA Software Design Flow Considerations for PA MMIC Design

In this white paper, a gallium arsenide (GaAs) pseudomorphic high-electron mobility transistor (pHEMT) power amplifier (PA) design approach is examined from a systems perspective. It highlights the design flow and its essential features for most PA design projects by illustrating a simple Class A GaAs pHEMT monolithic microwave IC (MMIC) PA design using Cadence® AWR® Microwave Office® circuit design software. The paper begins with the concepts of design closure and then describes parametric design as key concepts to understanding each step of the PA design process.

Advanced Channel Emulator

The ACE9600 builds upon the SLE900 by adding Payload impairment capability, synchronization of up to 16 channels, 12 tap multipath fading, and 600 MHz of instantaneous bandwidth. The instrument can be configured with 1 to 4 channels. Link impairments include delay, Doppler, attenuation, phase offset, AWGN, frequency hopping, and multipath fading. Payload impairments include IMUX/OMUX emulation (amplitude and delay distortion), amplifer compression effects (AM/AM and AM/PM), phase noise, and spurious signals. Parameters can be set to fixed values in Static mode, or continuously changed in real time in Dynamic mode without phase discontinuities.
