A Primer on Quadrature Amplitude Modulation (QAM)

While other modulation schemes discussed in this blog series (pulse, frequency, amplitude, phase) date back to the early chapters of RF engineering history, quadrature amplitude modulation (QAM) was first described by C. R. Cahn in 19602 and evolved steadily over the next few decades.  In the last 25 to 30 years, no modulation scheme has seen such widespread development and application as QAM. The technology has played a pivotal role in the industry’s ability to scale data speed and capacity with user demand by packing more data onto the carrier waveform and pushing a fixed channel bandwidth closer to Shannon’s limit. QAM modulation is used widely in cellular networks and backhaul, CATV networks and fixed wireless access points (802.11), and satellite communications to name a few. 

This article describes QAM using basic mathematics and illustrate how a QAM modulator operates.

Waveguide Amplifier WVA-60903G+

+21 dBm Power for E-Band OTA Testing

Mini-Circuits continue to grow the amplifier lineup for millimeter-wave test applications with the introduction of the WVA-60903G+ E-Band WR12 waveguide amplifier. The model covers the entire 60 to 90 GHz range with 29.5 dB gain, ±1.5 dB gain flatness and +21 dBm saturated output power and makes it an ideal driver amplifier for high-frequency test sets such as automotive radar, 5G FR2 network equipment, millimeter-wave backhaul et cetera.
