QMSIM 4.0

QMSIM is a computer skill that enables the generation of various RF modulations such as QPSK, QAM, OFDM, FM, PM, AM, and pulsed Doppler. The QM and AM series modulators use active and passive designs respectively, and feature integrated LO amplifiers for superior linearity.

Quadrature modulators generate any bandpass RF modulation including QPSK, QAM, OFDM, FM, PM, AM, and pulsed Doppler. I and Q baseband inputs directly modulate the LO input to generate a modulated RF output.
AM series modulators use active designs with superior linearity and have integrated LO amplifiers. QM series modulators are passive for the lowest output noise.
