This integrated RFID transmitter includes an upconversion mixer and power amplifier for generating high-output voltage waveforms with relatively high efficiency from 860 to 960...
By using a simple coplanar-waveguide (CPW) feed and two resonant structures, this relatively simple antenna can cover the full UWB frequency range with notches for two occupied...
The use of a novel C-shaped slot helps define band-notched characteristics for this broadband microstrip antenna design for use across the UWB frequency band.
Dr. Ahmed Boutejdar and Dr. Abbas Omar Novel circuit design elements such as defected-ground-structure (DGS) resonators and electromagnetic-band-gap (EBG) structures have helped...
Based on the shape of a half-periodic sinusoid, this novel antenna features CPW feedlines and compact size while covering the full 3.1-to-10.6-GHz UWB range.
This analysis of a phase-lock-loop frequency synthesizer highlights the importance of the loop filter in final synthesizer performance, and how to analyze the noise contributions...
This filter achieves dual passbands with high selectivity in a compact size by using asymmetrical separated spirals resonators embedded in microstrip transmission lines.
Function generators are typically used to produce high-frequency square waves, although the specifications used to describe output frequency performance are often misleading. ...
The trick is combining self-injection locking with mode-coupling techniques to shave the size, cost, and phase noise from voltage-controlled crystal oscillators (VCXOs).
This linear, low-noise amplifier spans a range of 2.1 to 7.0 GHz with low noise and reasonable gain while consuming less than 8 mW power from a +0.8-VDC power supply.
This compact three-way power divider provides an unequal dividing ratio of 4:1:1, with broad bandwidth centered at around 4 GHz, for WiMAX and WLAN applications.
