    Medical technology has improved remarkably over the past few generations, becoming more sophisticated and less invasive as the years progress. Now, with microwave Doppler radar phase modulation, noncontact respiration and heartbeat monitoring offers an attractive alternative to commonly prescribed chest-strap monitors. Doppler radar uses double-sideband transmission for vital sign detection from f... View full abstract»

    In this article, analytic and optimization-based methods for the synthesis of dual-passband microwave filters are presented. First, the frequency transformations for synthesizing dual-passband filters is described. For the filters in which the reflection and transmission zeros cannot be found analytically using frequency transformations, an optimization (or trial-and-error) procedure for a systema...

    In this article, a high-power, high-efficiency inverted Doherty power amplifier (PA), having a more compact load network than that of the conventional Doherty amplifier, was designed and implemented for wide-band code-division multiple access (WCDMA) base-station applications. Its configuration and working principle are compared with the conventional Doherty amplifier. For experimental verificatio... View full abstract»

    On the basis of the current status of silicon based MMICs, it is possible to implement millimeter-wave SOC in silicon-based technologies that include the antenna, a medium-power amplifier, a transceiver, an LO (frequency synthesizer), and baseband circuits in a single chip. With certain interconnection schemes, such as flip-chip, to connect the chip to the substrate, it is also possible to integra... View full abstract»

    The IEEE MTT-5 student design competition for high-efficiency PAs provides the opportunity for the student to do an in-depth study of a PA from theoretical concept and analysis to fabrication and testing. This competition motivates many students to have a strong interest in a highly efficient PA design and development. The contest rules require the PA to operate at a frequency greater than 1 GHz b...

    In this article, a novel reconfigurable bandpass-bandstop filter based on the varactor-loaded closed-ring resonators is presented, where the bandpass and bandstop characteristics can be easily controlled by tuning the varactor bias voltage. This reconfigurability results from the perturbation effect on the degenerated even and odd modes of the closed-ring resonator. When the perturbation varactor ... View full abstract»
