The modern, advanced CMOS direct radio frequency (RF)-sampling data converter has been eagerly awaited by system design engineers for several major end-equipment manufacturers. This includes ...

Communications receiver architecture has evolved slowly over the years. The most common and successful configuration is the superheterodyne architecture, which translates the incoming signal to a ...

Many systems divide a crystal frequency by an integer number to generate clock signals. Unfortunately, the integer divisor limits the available set of output frequencies. Applications such as ...

The critical component in all digital communications receivers is the analog-to-digital converter (ADC). The ADC sampling rate, bandwidth, and noise tolerance establishes the specifications and ...

ST-Ericsson’s Thor M7450 LTE-Advanced modem, currently being sampled, uses a single radio for carrier aggregation. Called M7450, it supports all relevant 3GPP specified frequency bands having 10 ...
