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...

An Introduction to the History, Principles and Applications of AM Radio When you think of advancements in signal modulation, your mental time machine might go back to the turn of the 21st century and LTE which was proposed by NTT DOCOMO as “Super 3G” in early...

Mini-Circuits offers QPSK (quadrature phase-shift keying) and I&Q modulators from 10% bandwidth to as much as 5:1 octave span. So there’s no longer any need to gather double-balanced mixers and 0° and 90° hybrids to assemble “in-house” QPSK or...

QPSK Modulators Q: What is the difference between a bi-phase modulator and a quadrature (QPSK) modulator? A. The bi-phase modulator has two phase states, 0° and 180°, modulated by switching polarity of the dc voltage at the control ports. The basic elements in a QPSK...
