November 2004 - In This Issue [Cover Story] Polar Modulator Saves Power In EDGE Sets Data is playing an increasingly important role in cellular handsets, requiring new designs to receive and transmit data as well as voice. The transition from circuit−switched to packet-based radios, demonstrated by the success of GPRS, has... — Frank Della Corte , et al. [News] Merrimac Grows Into Second Half-Century Fifty years brings with it many changesin the case of Merrimac Industries (West Caldwell, NJ), most for the better. Founded in 1954, the 50-year-old microwave pioneer has been highly regarded for its ability to solve technical challenges with... — Barry Manz [News] Devices Advance At 2004 IEDM Advances in device technology make possible modern electronic marvels such as the cellular telephone and the Personal Digital Assistant (PDA). Device designers continue to push the envelopes of integration and performance to meet customers' needs... — Jack Browne [Design Features] Designing A Low-Noise VCO Transmitters and receivers for license-free industrial-scientific-medical (ISM) and short-range-device (SRD) bands require fairly high-performance voltage-controlled oscillators (VCOs). For example, ISM and SRD integrated circuits (ICs) must meet... — Andreas Laute , et al. [Design Features] Applying The Operating Gain Design Approach Amplifier designers have so far learned about the use of the unilateral gain design approach as well as a method for achieving simultaneous conjugate matching of a stable transistor's input and output ports to its source and load. This month, the... — Joseph F. White [Product Technology] Services Speed Thin-Film Designs Thin-film circuitry supports a wide range of active and passive components and assemblies in microwave systems. In order to design and manufacture such circuits, a host of precision machines and wide array of expertise is needed. Fortunately, CTT,... — Jack Browne [Editorial] Making A List And Checking It Lists have intrigued readers since childhood. Most of us can remember lists made during a holiday season, or a list of New Year's resolutions (often ignored). Most high-frequency specifiers, for example, refer to the "short list" of favored... — Jack Browne |
