    I have from time to time talked about cultural differences in electronics in this column, usually focussing on the divide between lower frequency analog design, and microwave techniques at GHz frequencies. This leaves something of a gray area in the middle, which we loosely term RF (this stands for radio frequency, in the unlikely case any readers were unaware of this, but IEEE copy editors insist...

    In this article, a brief introduction to the development of tunable filters was given. A classical design technique based on a combline filter approach was shown, where minimum degradation in passband performance could be obtained across a broad-tuning range. The fundamental disadvantages associated with the conventional resonator tuning approaches were also discussed, recognizing the importance o... View full abstract»

  • Tuning in to RF MEMS

    RF MEMS technology was initially developed as a replacement for GaAs HEMT switches and p-i-n diodes for low-loss switching networks and X-band to mm-wave phase shifters. However, we have found that its very low loss properties (high device Q), its simple microwave circuit model and zero power consumption, its high power (voltage/current) handling capabilities, and its very low distortion propertie...

    Electronically reconfigurable or tunable microwave filters are attracting more attention for research and development because of their increasing importance in improving the capability of current and future wireless systems. For instance, emerging ultrawideband (UWB) technology requires the use of a wide radio spectrum. However, the frequency spectrum as a resource is valuable and limited, so the ... View full abstract»

  • High-Q tunable dielectric resonator filters

    Tunable dielectric resonator filters can potentially address wireless and satellite applications that require very high Q values (4,000 and up) with a limited tuning range (less than 15%). Such high Q requirements cannot be met by any other known non-superconductor tunable filter technology at the present time. The intent of this paper is to provide newcomers and end users with the current status ... View full abstract»

    This article gives an overview of applications of radio frequency (RF) microelectromechanical system (MEMS) technology in radio detection and ranging (radar). RF MEMS components for radar include attenuators, limiters, (true-time-delay) phase shifters, transmit/receive (T/R) switches and tunable matching networks. Radar subsystems that benefit from RF MEMS technology include active electronically ... View full abstract»

    The National Institute of Standards and Technology (NIST) recently introduced a new electronic approach for verifying microwave vector- network-analyzer (VNA) calibrations with a single computer-controlled electronic verification artifact. The verification results are captured in easy-to-understand performance metrics that, unlike those derived from measurements of mechanical verification artifact... View full abstract»
