Linear Actuators with Integrated Connector

August 29, 2007 6:14 am | Product Releases | Comments

Haydon Switch & Instrument, Inc. announces its size 11 hybrid linear actuators with an integrated connector. Offered alone or with a harness assembly, this connector is RoHS compliant and features a positive latch in order for high connection integrity. The connector is rated up to 3A and the mating connector will handle a range of wire gauges from 22 to 28.

Simulating the Effect of Blockers on Data Converter Performance in Wideband Receivers

August 29, 2007 5:57 am | by Michael Sink and Pamela Aparo, Analog Devices | Articles | Comments

Many different standards for wireless communications equipment are in use today. Narrowband communication standards use stronger transmission in a small slice of bandwidth. Wideband standards use lower transmission power across a larger bandwidth. Each standard defines minimum performance characteristics for receivers, and includes specifications such as bandwidth, maximum signal level, and sensitivity. GSM is one narrowband example; the channel bandwidth is 200 kHz. A GSM receiver must have a minimum sensitivity of –104 dBm and be able to tolerate a –13 dBm signal at the antenna. In contrast, CDMA2000 is a wideband standard that uses a 1.25 MHz bandwidth. CDMA2000 receivers need to have a minimum sensitivity of –117 dBm/1.25 MHz and tolerate a maximum signal of –30 dBm at 900 kHz offset.1

8-Bit MCUs Keep Going Strong

August 29, 2007 5:22 am | by Jon Titus, Senior Technical Editor | Articles | Comments

"Cost still rules applications," said Ross Bannatyne, Marketing Director at Silicon Laboratories, a supplier of 8051-based MCUs. "If 8-bit MCUs solve problems, why use more expensive 32-bit chips?" Newer 8051 derivatives, for example, execute 100 MIPS and on-chip multiply-accumulate accelerators let them handle signal-processing tasks. According to Bannatyne, some engineers might not realize 32-bit MCUs can incur code penalties. "They might assume an algorithm that requires 16 KB in an 8-bit MCU also needs 16 KB in a 32-bit processor. Often the code takes more memory in the 32-bit processor, often much more."
