... IF-based double upconversion systems. In addition to offering excellent linearity and noise perfor- mance, the MAX2022 also yields a high level of compo- nent integration. This device includes two matched passive mixers for modulating in-phase and quadrature signals, three LO mixer amplifier drivers, and an LO quadrature splitter ...

... The two-stage LO amplifier allows a wide input power range for the LO drive. While a nominal LO power of 0dBm is specified, the MAX2022 can tolerate LO level swings from -3dBm to +3dBm. The MAX2022 modulator is composed of a pair of Phase Splitter matched double-balanced passive mixers and a balun. The I and Q differential baseband inputs accept signals ...

... For GSM, connecting a 1nF capacitor from COMP to ground is recommended for filtering out noise and frequency offsets above 600kHz. The MAX2022 I and Q baseband inputs should be dri- ven differentially for best performance. The baseband inputs have a 50Ω differential input impedance. The optimum source impedance for the I and Q inputs is 100Ω ...
