Driving the QM Series Quadrature Modulators
This note outlines several methods of interfacing the QM series modulators to single-ended and differential I/Q sources including modern D/A converters. From Polyphase Microwave.

Interface Circuits for the QD Series Quadrature Demodulators

This application note presents several circuit ideas for interfacing the differential I/Q outputs of the QD series demodulators to single-ended loads and modern differential A/D converters. From Polyphase Microwave.

Modulation Techniques for Low-Cost RF Data Links

In radio frequency applications there are many techniques to choose from. Some, such as Carrier-Present Carrier-Absent (CPCA), are very simple and inexpensive to implement, while others, such Gaussian Minimized Shift Keying (GMSK), allow for very efficient use of bandwidth at high data rates. Other modulation techniques include Frequency Shift Keying (FSK), Phase Shift Keying (PSK), Quadrature Modulation, Direct Sequence Spread Spectrum (DSSS). By Linx Technologies.

Orthogonal Frequency Division Multiplexing

This tutorial discusses Coded Orthogonal Frequency Division Multiple Access (COFDMA) technique.

Unraveling Modulation Quality in Mobile WiMAX™ Uplink and Downlink with Multiple Zones and Bursts
White paper By: VISWANATHAN GANESAN WiMAX Application Engineer, Agilent Technologies. This article delves into the complexities associated with digital demodulation of Mobile WiMAX uplink (UL) and downlink (DL) signals. It covers the modulation quality measurement required for Mobile WiMAX transmitters and provides a recommendation of the best tools to use for developing Mobile WiMAX products.
