3G Tx Direct Up Conversion

Analog Devices’ 3G base station solutions for transmitter direct up conversion architectures produce less mixing spurs, require less filtering, lower power consumption, and fewer components in the signal path solution. A transmit DAC, IQ modulator, LO synthesizer, RF VGA and RMS power detector form the core of the up conversion signal path.

A Key Concern in IF Sampling is that of Aperture Uncertainty (Jitter)

AN-417: Fast Rail-to-Rail Operational Amplifiers Ease Design Constraints in Low Voltage High Speed Systems (pdf, 234,127 bytes)
Movement towards lower power supply voltages is driven by the demand that systems consume less and less power coupled with the desire to reduce the number of power supply voltages in the system. The following applications are discussed: Single-Ended and Differential Input ADC Input Circuits, Video Line Driver, Active Filter, HDSL Transceiver, and Transformer Drive Circuits.
