Introduction. When generating analog or digital FM for communications applications, an IQ modulator provides a versatile and low-power solution. An example design will show how a mixed-signal MCU is used to perform the phase accumulator and sine/cosine lookup table functions. The importance of IQ Modulator accuracy and linearity is demonstrated.
