| Increased Browsing Will Fuel Mobile WiMAX By Jack Browne, MWRF Technical Director WiMAX supporters hoping for the marriage between Sprint and Clearwire were clearly disappointed earlier this month when the two companies were unable to come to terms on a WiMAX partnership. The two firms had hoped to create a nationwide WiMAX operation that would cover both large metropolitan and mid-sized markets in the United States. Unfortunately, Sprint's recent poor financial performance turned into a stumbling block for the WiMAX joint venture, although representatives from both companies have not ruled out the possibility of the two communications service providers teaming on some form of a WiMAX partnership in the future. In spite of this "speed bump," the growth of mobile WiMAX appears inevitable. Given the appetite in this country for Internet web browsing, and the desire for mobility, devices such as WiMAX-enabled cellular telephones will provide broadband Internet access anywhere within a WiMAX network. Information on WiMAX is plentiful, with industry companies invited to visit the WiMAX Forum (www.wimaxforum.org) or WiMAX.com (www.wimax.com) for more information. In addition, the IEEE (www.ieee.org) is offering a Webcast on December 5th, "WiMAX: Ready for Prime Time," moderated by former Wireless Systems Design Editor, Ron Schneiderman. As with Bluetooth and WLAN wireless technologies before it, considerable industry firepower supports fixed and mobile WiMAX, making it a good bet for future success. | ||

| Lockheed Martin Picks Phase Matrix For DTO Phase Matrix has won a $700,000 contract from Lockheed Martin Systems Integration- Oswego to develop an X/Ku-band digitally tuned oscillator (DTO) for the United States Air Force's B-2 stealth bomber. Integration of the DTO is part of the modernization of the B-2's electronic systems. The DTO design is based on low-phase-noise, fast-tuning voltage-controlled oscillators (VCOs) that are digitally linearized for excellent frequency accuracy with low drift over temperature and across the tuning range. According to noted oscillator designer Dr. Paul Khanna, Vice-President of Phase Matrix, "This contract fully reflects Lockheed Martin's confidence in our company and in the ability of our Components Group to meet the challenging requirements of a critical component for the B-2 bomber." Khanna added that the contract "also affirms our capabilities in the field of complex microwave subassemblies." Phase Matrix's Components Group offers extensive lines of products from 1 to 50 GHz for instrumentation, military, and telecommunications applications, including fixed- frequency and phase-locked oscillators. The company's custom subassemblies are based on a wide range of analog and digital functions, including integration of switches, oscillators, filters, attenuators, frequency conversion, power supplies, microprocessors, and memory.

| Tyco Adds RoHS Coaxial Connectors Tyco Electronics Corp. has announced a new line of RoHS-compliant RF coaxial connectors for a variety of applications, including test and measurement equipment, industrial process and control equipment, and medical equipment. The ZDC family of connectors are based on die-cast components and thermoplastic dielectric materials. They are designed with a bayonet coupling mechanism for applications requiring rapid connectivity and threaded coupling for applications requiring secure terminations. Initial models are available in BNC interfaces and a range of cable-mounted plugs and jacks as well as bulkhead and printed-circuit-board (PCB) sockets. Connectors can be supplied for 50 and 75 ohm systems at operating frequencies from DC to 40 GHz. The ZDC connectors meet MIL-C-39012 and MIL-STD-348A requirements. | ||
