Mixer Technologies for Modern Microwave and Wireless Systems Stephen Maas Applied Wave Research, Inc. Abstract: Although mixer design is often viewed as a mature technology, there seems to be no end to the supply of creative new ideas for mixer circuits, or for new needs. Today, the needs of system designers are evolving from high-performance circuits to low-cost, manufacturable, and integrable de

Millimeter-Wave and Terahertz Devices Based on MEMS Concepts Hans L. Hartnagel Institut fuer Hochfrequenztechnik, Technische Universitaet Darmstadt Merckstr. 25, 64283 Darmstadt, Germany email: hartnagel-hf.tu-darmstadt.de The higher the frequency, the more significant are the losses. Therefore it is important even for semiconductors with relatively large energy gap to remove as much semiconducti

Semiconductor laser sources for datacom and telecom applications: recent trends Marina Meliga Agilent Technologies, marina_meliga-agilent.com A brief review of current options for semiconductor laser sources for different network segments: LAN (Local Area Network), MAN (Metropolitan Area Network) and WAN (Wide Area Network). and tunable sources for WDM systems (used in MAN and WAN) are becoming mo
