| Renewed Interest In Military Electronics By Jack Browne, MWRF Technical Director Wireless applications brought many commercial opportunities to this industry. As an example, for chip makers like RF Micro Devices (www.rfmd.com), cellular handsets represented the opportunity to manufacture and ship millions of integrated circuits (ICs) for front-end functions. More recently, an article appearing in the November issue of Microwaves & RF showcases the company's efforts in supplying modules and ICs to the emerging Universal Mobile Telecommunications Systems (UMTS) market. Perhaps lost in the steady growth of commercial wireless applications is the similarly strong growth in military-electronics opportunities. One clear sign of this is to follow the moves of the capital-equipment suppliers, such as test-equipment companies. In recent months, activities at major companies such as Aeroflex, Agilent Technologies, Anritsu, and Rohde & Schwarz have led to the release of products aimed at pulsed or multi-emitter testingthe types of tests performed by companies engaged in the manufacture of components and subsystems for such platforms as electronic-warfare (EW) receivers and radar systems. This industry cut its teeth on military electronics and, in spite of the commercial opportunities, remains close to the needs of military applications worldwide. | ||

| Plastic Optical Fiber Sends 40 Gb/s Discovery Semiconductors has provided the University of Kiel (Kiel, Germany) with a multimode coupled 40-Gb/s photodiode for the institution's research on high-speed optical communications over plastic optical fiber (POF) and multimode fiber (MMF). So far, the device has been used as part of a demonstration of error-free 40-Gb/s transmission across 50 m of POF by researcher Stefan Schoellman. The research was presented at the recent European Conference on Optical Communications (ECOC) in Berlin, Germany and is part of Professor Werner Rosenkranz's research group at the University of Kiel. Professor Rosenkranz notes," This work demonstrates that 40 Gb/s transmission is possible over POF and MMF. These fiber types usually support only low bit rates. The multimode-coupled photodiode from Discovery is a key enabling technology which allows 40 Gb/s transmission over POF." | ||

| Synergy Launches Optimized-Bandwidth VCOs Synergy Microwave has developed a line of voltage-controlled oscillators (VCOs) optimized for use over specific bandwidths. An example of the new line is model DXO810900-10, which tunes from 8100 to 9000 MHz with tuning voltages of 0.5 to 24.0 V. The oscillator delivers at least -2 dBm output power with -84 dBc/Hz phase noise offset 10 kHz from the carrier and typical harmonic suppression of 35 dB. The surface-mount VCO measures just 0.3 x 0.3 inches and draws 35 mA maximum current from a +10-VDC supply. | ||
