It is shown that if certain essential broadband noise performance goals are met, the use of direct quadrature modulation can have a significant impact on reducing size, weight and power consumption of mobile phones.
The model RF9958 transmit IC integrates three functions into a single QSOP-28 package: quadrature modulation, variable-gain amplification and upconversion, as shown in Figure I.
With quadrature modulation, the ideal phase difference between I and Q signals is 90 [degrees].
