Snap-in Aluminum Electrolytic Capacitor

December 10, 2001 3:33 am | Comments

Because of the continued push for higher energy density and smaller size in motor drives, UPS systems and power supplies, there is a growing demand for increased ripple-current capability in bus capacitors. It's the bus capacitors that take the heat from equipment downsizing because the new designs impose more ripple current per capacitor and use fewer or smaller capacitors....

Base Station Synchronization in Wireless Networks: Cellular, Fixed Broadband, Wireless LAN

December 6, 2001 5:25 am | Comments

Datum-Irvine Wireless networks come in many different flavors, from the familiar cellular phone network to fixed broadband to wireless LANs. Although each is a very different application they are all dependent on a common base station architecture. The base station, (also called cell site, picocell, or access point depending on the technology) is the connection point between the wired and wireless world....


Multi-Monitor Support Added to Logic Analyzer

December 5, 2001 4:00 am | Comments

Tektronix announced important new advancements to its flagship platform for digital signal integrity. Leading computer and embedded system makers are developing increasingly complex digital devices, which equates to more signals on a logic analyzer's screen at one time. Until now, engineers have been limited to one monitor, scrolling up and down constantly to compare data, and toggling between application windows to work concurrently with t...

December 3, 2001 3:38 am | Comments

Maxim Integrated Products introduces the MAX3362 high-speed RS-485/RS-422 transceiver. This device is packaged in an 8-pin SOT, saving 70% board space over the industry-standard SO. In addition, the MAX3362 features hot-swap circuitry, eliminating data glitches during hot insertion. This circuitry holds the RS-485/RS-422 lines in a high-impedance state during startup to avoid sending false data....

High Performance Base Station Antennas

December 3, 2001 3:38 am | Comments

Radio Waves announced the availability of new high performance base station antennas in the ISM, 3.5 GHz, and UNII bands. These 90-degree sectors offer exceptional sidelobe roll-off characteristics. With a half power beamwidth (HPBW) of 90 degrees, the roll off is more than 25 dB at ± 135 degrees, and the Front-to-Back ratio is greater than 35 dB....


36 to 40 GHz GaAs MMIC Up-Converter

December 3, 2001 3:38 am | Comments

Mimix Broadband announced the introduction of a gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) up-converter, which is comprised of a pair of sub-harmonic mixers configured to form an image reject mixer. This is followed by a two stage low noise amplifier (LNA). The image reject mixer removes the need for a bandpass filter after the mixer to suppress the unwanted sideband....
