Circuit provides 70 dB of AGC
Ben Segal, Telecommunications Technology, Sunnyvale, CA; Edited by Margery Conner and Fran Granville, February 2, 2012A comparator autoranges to ensure that the automatic-gain-control section sees a signal between −60 and −25 dBm, keeping the FET in its linear region. More -
Sorting out 4G: Are we there yet?
Janine Love, Contributing Editor, January 30, 2012Thanks to clever marketing campaigns and branding, the general public believes that 4G has arrived. The performance of 4G/LTE mobile handsets has improved, and designers are pushing the outer limits of performance in all parts of the handset. In many cases, the limitation is available spectrum, so designers must develop creative approaches until governments act. More -
TI ups its smart grid offerings
Nicolas Mokhoff, EE Times, January 23, 2012Texas Instruments claims the industry's first demonstration of a radio frequency system-on-chip that integrates an IEEE 802.15.4 (2.4 GHz) radio, an ARM Cortex-M3 processor, and enough flash and RAM to run the ZigBee IP stack and SE2.0 profile. More -
