EMXOs boost oscillator performance with lower power consumption and reduced size
Advances in the evacuated miniature crystal oscillator (EMXO) manufacturing process have enabled EMXOs to achieve performance comparable to oven-controlled oscillators with lower power consumption and lower cost. While describing the performance of EMXOs, this article discusses its benefits in satellite applications and provides a design example....
Direct synthesis of WiMedia UWB signals
Although UWB promises high data rates, creating these signals in the lab and preserving their signal integrity is a highly complex process. One unique method of creating UWB-WiMedia signals uses an arbitrary waveform generator (AWG), yet retains the simplicity of using a dedicated UWB chipset. RF design engineers who use this unique method of AWG-based WiMedia signal generation will have several options, including IQ-baseband, IF and direct-RF-synthesis signal-generation techniques....
