Element Efficiency and Noise in Grid Arrays - Microwave Theory and Techniques, IEEE Transactions on
نویسندگان
چکیده
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 radiation pattern of grid arrays. The results are also extended to show that the output noise temperature of the entire array will be the same as the output noise temperature of a single element.

Properties 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...
متن کاملA Terahertz Grid Frequency Doubler - Microwave Theory and Techniques, IEEE Transactions on
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 mea...
متن کاملQuasi-Optical Transmit/Receive Front Ends - Microwave Theory and Techniques, IEEE Transactions on
Quasi-optical (QO) active circuits have originally received interest for power generation by large-scale power combining of solid-state devices at microwave and millimeter-wave frequencies. Here, we present an overview of QO components developed with functionality in mind, with an emphasis on bidirectional amplifier arrays for transmit/receive (T/R) front ends. We discuss possible advantages of...
متن کاملMultitone Frequency-Domain Simulation of Nonlinear Circuits in Large- and Small-Signal Regimes - Microwave Theory and Techniques, IEEE Transactions on
Computer simulation of general microwave nonlinear circuits excited by a large number of input tones is addressed. The algorithm, based on the spectral-balance method, uses novel index-vector and convolution-matrix generation techniques. That, in conjunction with a new nonlinear-device modeling approach (which directly takes into account the higher order derivatives of the I=V and Q=V character...
متن کاملAntenna applications of superconductors - Microwave Theory and Techniques, IEEE Transactions on
The applicabilty of superconductors to antennas is examined. Potential implementations that are examined are superdirective arrays; electrically small antennas; tuning and matching of these two; high-gain millimeter-wavelength arrays; and kinetic inductance slow wave structures for array phasers and traveling wave array feeds. Superdirective arrays and small antennas will not benefit directly, ...
