GPS clock helps locate wireless 911 callers

Article Abstract:

TruePosition Inc. will collaborate with Trimble Navigation Ltd. to offer a system that will allow 911 emergency dispatchers to locate the position of a wireless-phone caller within regulatory stipulations. Trimble's Global Positioning System (GPS) clock will be used in TruePosition's Wireless Location System to provide precise timing synchronization between location receivers to locate an emergency caller's handset. TruePosition vice president and general manager Louis Stilp notes that precise timing synchronization is a vital requirement for their system to support the Federal Communications Commission's E911 mandate, which requires such a locator system to ascertain a caller typically within 125 meters, by October 1, 2001.

LDMOS multicarrier amplifier powers cellular base stations

Article Abstract:

AML Communications' new Microcell 150 LDMOS multicarrier amplifier, a modular system that accommodates as many as four plug-ins for a power output of from 36 W to 150 W, incorporates laterally-diffused metal-oxide-semiconductor (LDMOS) technology. LDMOS have been found to provide a roster of advantages over earlier silicon-bipolar instruments, used in power-amplifier modules for boosting outgoing signals at cellular-telephone base stations. The Microcell 150 also encompasses a unique Windows 95-based control and monitoring system, which allows the download of several operating parameters via an RS-232 interface for observation by station technicians.

ECM receiver integration reduces package size

Article Abstract:

Akon Inc. of San Jose, CA, offers a new electronic-countermeasures (ECM) channelized receiver, which combines into an aluminum structure monolithic microwave integrated circuits and microwave integrated circuits. Akon's new ECM channelized receiver, which offers benefits such as a substantial reduction in size and receiver's costs, performs virtually all of its functions using the monolithic microwave integrated circuits and microwave integrated circuits. The firm's new ECM channelized receiver also offers greater reliability levels as a result of its lower resistance to thermal conditions.
