This article describes how a channel emulator can be used to characterise the performance of a MIMO receiver. The testing was done in stages of increasing complexity, namely, testing under AWGN conditions, MIMO testing with known static channels and, finally, testing with channels chosen to represent ‘real world’ behaviour.
austriamicrosystems has released the AS8221 FlexRay standard transceiver, certified to the latest FlexRay standard V2.1 Rev B.
Digi International has introduced the Connect WAN 3G IA, a third-generation (3G) wireless WAN router for secure primary and backup connectivity to remote devices in severe environments.

Sitrans LR 460 is a continuous radar level measurement transmitter featuring 24 GHz FMCW (frequency-modulated continuous wave) and process intelligence echo processing.
Renesas Technology is collaborating with IMEC on research into 45 nm RF transceivers targeting Gbps cognitive radios.
At the Institute of Electrical and Electronics Engineers (IEEE) taskgroup meeting in Hawaii recently, there was an agreement over the next high speed Wi-Fi standard, 802.11n.
Mimix Broadband, Inc. has announced the introduction of a gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) 13/15 GHz chip set that consists of a highly integrated image reject receiver and transmitter, and compact, two stage power amplifier. The image reject mixers eliminate the need for an image bandpass filter after the amplifier to remove thermal noise at the image frequency.
