Hands On: Improve performance in RF transceiver designs Product How-To 10/18/2011 Post a comment This paper describes ZIF and superheterodyne receiver differential interfaces for the demodulator, IF VGA, mixer, and analog port of the ADC, as well as transmitter differential interfaces between the TxDAC and FMOD, using Analog Devices parts for active portions of the signal chain. Gain calculations and simulation results are presented for the application filters that were designed for these circuits.
Wireless window contacts benefit from energy harvesting sensors Research 10/16/2011 3 comments Research scientists at the Fraunhofer Institute for Microelectronic Circuits and Systems IMS in Duisburg have now developed wireless window contacts which indicate when a house's windows are open or closed. The fail-safe system uses sensors that harvest the energy they need to run from ambient radio signals.

Wall switch brings 802.11n Wi-Fi to hotels News & Analysis 10/1/2011 1 comment Ruckus Wireless announces that its high-speed Wi-Fi wall switch has experienced broad adoption by hotels around the globe looking to deliver a myriad of IP-based in-room services over a unified wired/wireless infrastructure, while also providing high-speed wireless Internet access to a flood of new Wi-Fi-enabled mobile and handheld devices.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
