Quadrature Amplitude Modulation Emulator QAME datasheetpresentation

QAM Emulator delivers QAM 16 and QAM 64 respectively on first and second outputs from a QPSK input signal. The device performs a 3-path interference with 500ps delay between each arm. This delay is customizable at the order. A stable fine phase tuning system is implemented enabling a perfect control of the phase of the constellation . In the same way, and as an option, the power balancing between the arms can be user tunable.  If this option is not chosen, the power balancing is factory set. .
