Compiled by Marcy Koff
The code-division multiple access (CDMA) 50-ohm matched 6-mm- square power amplifier is suitable for personal communication services, wireless local loop, and other high-bandwidth wireless data markets. The InGaP HBT amplifier module is less than half the size of comparable solutions, integrates 14 supporting components, and meets continuing requirements for small, high-capacity wireless voice and data applications. The CHP1232-PM power module is a linear-efficient three-stage power amplifier developed for PCS CDMA handsets and infrastructure systems. Features include operation as low as 3.2 V from a single positive supply, 30-dB gain at operating output power, and +28-dBm output power. The unit measures 6 mm square by 1.7 mm high.

High-performance small computer systems interface (SCSI) cables are based on the 0.8-mm contact-pitch standard. These small-form-factor cables are designed for high-density computer systems and enable up to four wide 16-bit SCSI cables to plug into the back of a single PCI card. The cables use a direct- attach method, which enables the conductors of the cable to be directly attached to the PC board inside the connector.

Test tablet and modules
The N XT modular network test platform uses the Windows CE Operating System and has a built-in Type II PCMCIA slot, which supports unlimited flash memory, modem communications, and Ethernet attachment. The platform features an expandable design, which gives the user flexibility to perform a multitude of tests spanning LAN/WAN/telco through Xpand modular technology. Xpand modules plug directly into the N XT platform. The X.A.C.T. module is used for fiber-optic verification and Category 6 certification while the XAMINE module does network diagnostics and analysis. The N XT Network Test Tablet, Xpand modules, and XAMINE diagnostic analyzer are priced at $2,295, $6,600, and $1,495, respectively.
The Powermax 8 Tel surge protector safeguards a computer system with a modem or other telephone line. The protector's joule technology can handle an unlimited number of surges. The company guarantees that the unit will protect equipment no matter how big the surge may be. The device either absorbs and reroutes the surge energy to ground or, in the event of a catastrophic surge over 1,020 joules, the unit disconnects the power to the equipment. The surge protector has eight protect AC outlets, all spaced to accommodate transformers for maximum flexibility. Four outlets are always on and four are switched. It comes with EMI/RFI noise filtration and a diagnostic light to indicate proper grounding. The unit is priced at $34.95.

MT-RJ fiber-optic adapters
Singlemode and multimode MT-RJ fiber-optic adapters provide twice the density of SC fiber adapters, accommodating 24 duplex fiber connectors in the same amount of space occupied by 12 SC fiber ports. The MT-RJ adapter family consists of three packages: an individual adapter, an adapter in a keystone package, and a six-pack modular panel. The keystone package adapters fit into modular network patch panels and faceplates. The six-pack modular panel is used in wall- or rack-mount fiber enclosures. The devices feature a self-latching mechanism similar to that found on standard copper RJ adapters and connectors. With typical insertion loss of <0.3 dB, these adapters are suitable for fiber-optic networks and fiber-to-the-desk applications.

MMTA annual telecommunications review and forecast published
One of the most useful and targeted publications that crosses my desk each year is the MultiMedia Telecommunications Market Review and Forecast, published by the Telecommunications Industry Association and its subsidiary, MultiMedia Telecommunications Association (TIA/MMTA-Arlington, VA).
This year's volume includes a summary of technical, economic, and public-policy activities during the preceding year, followed by extensive coverage of network services (such as local-exchange services and public pay phones) and technological solutions (such as Centrex and frame relay). Separate coverage is given to mobile and wireless communications, including cellular, personal communication services, and paging and messaging. Shorter chapters also deal with collaborative technologies like videoconferencing and computer-telephone integration.
The volume concludes with a look at international markets, including North American markets other than the United States, Eastern and Western Europe, Latin America, and Asia/Pacific (with special emphasis on the Asian economic crisis and its impact on the telecommunications market).
