Analog-to-digital converters (ADCs) are commonly used in receivers for wireless applications for either IF or baseband signal sampling. The choice of ADC is generally determined by the rest of the receiver architecture, and can be affected by the selectivity of the filters, the dynamic range afforded by the frontend amplifiers, and the bandwidth and type of modulation to be processed.
System sensitivity and noise The noise from each component in the front end adds to the receiver's noise floor, which sets the limit on the minimum signal level that can...
Intermodulation and Intercept Points The mixer generates intermediate freqeuency (IF) signals that result from the sum and difference of the LO and RF signals combined i...
Moving up the scale in complexity, we come to the next evolutionary RF architecture: the tuned-radio-frequency (TRF) receiver (see Fig. 8-6). This early design was one o... The fundamental operation of an RF front end is fairly straightforward: it detects and processes radio waves that have been transmitted with a specific known frequency o...
Infineon Technologies AG has announced the availability of its new generation 3G platform family. This new platform family addresses all major 3G market segments and incl...

The CDMA Development Group (CDG) (www.cdg.org) reported today that the 3G CDMA2000(r) subscriber base has nearly doubled since December 2002, reaching 60 millio...
One issue with comparator applications is caused when a slow-moving signal is applied to the input. As the applied signal crosses the switch point, even a small level of ...
