Fast Data Converters Advance Wireless Systems
Data converters can be thought of as the central cores of wireless-infrastructure systems. Complex signals must be digitized upon reception and converted to analog form for transmission. To meet the needs of present and future-generation wireless-infrastructure systems, analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) must therefore perform at RF rates and with outstanding linearity. The AD9444 ADC and AD9779...

RF RMS Power Detector Measures Two Signals Simultaneously
To support the data converters in wireless-infrastructure equipment, Analog Devices has introduced a dual-channel RF root-mean-square (RMS) power detector. This power detector measures transmit and receiver signal levels to 2.7 GHz. Known as the AD8364, the device can measure two complex input signals simultaneously. This integrated circuit is ideal for measuring the power levels of complex signals with constantly varying peak-to-average power levels, as in cdma2000, W-CDMA,...

Amplifiers Drive Broad Applications
General-purpose amplifiers (GPAs) can be thought of as the "RF glue" in wireless systems. Although they're simple in design, these amplifiers must boost RF signals to acceptable levels. They also must overcome the losses that are accrued by a...
