This quad-channel RF front end (and dual-channel sibling) enables direct sampling to 6 GHz without the need for additional frequency-conversion stages, eliminating local oscillators, mixers, amplifiers, and filters.

A simple dielectric resonator antenna design provides improved WiMAX performance in the 3-GHz band.

Advanced semiconductor fabrication is applied to the design of a beamsteered patch antenna array.

Silicon-on-glass waveguide are considered as transmission lines for terahertz-frequency integrated circuits.

A study by researchers from the University of Wisconsin-Madison sought the optimum antennas for applying electromagnetic radiation to cancerous tumors.

A line of Faraday isolators developed by SAGE Millimeter works over the total frequency range of 18 to 220 GHz.

This article, the second in a five-part series, focuses in on the synthesizer phase noise sources outside the synthesizer chip, such as noise induced in the voltage-controlled oscillator by power supplies and by the various loop-filter forms.

Wrapping up this series on microstrip antennas, attention turns to series feeds for microstrip array antennas along with the series/parallel combination technique.

This novel digital-to-analog converter can deliver output signals at Ka-band frequencies, dramatically simplifying communication-system designs.

These rugged rectangular waveguide filters provide low-loss passbands from 27 to 86 GHz for a growing number of applications at mmWave frequencies.
