A Terahertz Grid Frequency Doubler - Microwave Theory and Techniques, IEEE Transactions on

چکیده
We present a 144-element terahertz quasi-optical grid frequency doubler. The grid is a planar structure with bowtie antennas as a unit cell, each loaded with a planar Schottky diode. The maximum output power measured for this grid is 24 mW at 1 THz for 3.1s 500-GHz input pulses with a peak input power of 47 W. An efficiency of 0.17% for an input power of 6.3 W and output power of 10.8 mW is measured. To date, this is the largest recorded output power for a multiplier at terahertz frequencies. Input and output tuning curves are presented and an output pattern is measured and compared to theory.

Period-Doubling Analysis and Chaos Detection Using Commercial Harmonic Balance Simulators - Microwave Theory and Techniques, IEEE Transactions on
Two of the most common phenomena leading to chaos are the period-doubling cascade and the formation of transverse homoclinic orbits. In this paper, a bifurcation analysis technique is presented for the prediction of both phenomena in microwave circuits. The fact that the technique is based on the use of commercial harmonic balance software constitutes a major advantage for the circuit designer....

Ahsfrucf -Grid oscillators are an attractive way of obtaining high power levels from solid-state devices, since potentially the output powers of thousands of individual devices can be combined. The active devices do not require an external locking signal and the power combining is done in free space. In this work, 36 transistors are mounted on parallel brass bars, which provide a stable bias an...
متن کاملElement Efficiency and Noise in Grid Arrays - Microwave Theory and Techniques, IEEE Transactions on
The element efficiency of a phased array is the ratio of the radiated-to-available power of a single element, when only that element is excited. We relate this element efficiency to the output noise power generated by a quasi-optical grid amplifier array. Both electromagnetic and thermodynamic derivations will be presented. These ideas will be used to predict the total noise power and noise rad...

* D Abstract --Lossless broad-band microwave active inductors for generalpurpose use in microwave circuits are proposed and their characteristics are discussed. These active inductors are composed of a common-source cascode FET and a feedback FET, and operate in a wide frequency range with very low series resistance. A maximum Q factor of 65 is obtained. Theoretically, it can reach infinity. Fu...
متن کاملProperties of Periodic Arrays of Symmetric Complementary Structures and Their Application to Grid Am - Microwave Theory and Techniques, IEEE Transactions on
Deschamps’ theorem for n-terminal complementary structures is reviewed. An extension to Deschamps’ theorem for a class of three-terminal bounded structures with one axis of symmetry is presented. It is shown that, for these structures, a simple relationship between the impedances of the odd mode of the original structure and the admittances of the even mode of the complementary structure exists...
