QUADRATURE AMPLITUDE MODULATOR
QAM emulators enable to emulate a QAM signal from a QPSK signal.
With Kylia’s QAM16 or QAM64, you can emulate a QAM signal from a QPSK signal.
Phase tuning elements enable to adjust the delay between the different arms to a multiple of bit-time in order to optimize the interferences pattern.
