Design of compact monopulse standing wave slotted array in ku-band
(IEEE, 2019)
In modern radar and communication systems, high gain, high power capability and low-profile front-end antenna systems are frequently utilized. In this paper, a compact, lightweight, high reflection bandwidth and high gain ...
Cryogenic 1.2 to 116 GHz receiver for large arrays
(IEEE, 2018)
Current and future large arrays for radio astronomy are compared and the Next Generation Very Large Array, ngVLA, is introduced. Receiver requirements are described and a 4-feed system covering 1.2 to 116 GHz, in a single ...
An MMIC low-noise amplifier design technique
(IEEE, 2016-03)
In this paper we discuss the design of low-noise amplifiers (LNAs) for both cryogenic and room-temperature operation in general and take the stability and linearity of the amplifiers into special consideration. Oscillations ...
Broadband high power amplifier design using GaN HEMT technology
(IEEE, 2021)
This paper presents the design and measurements of a broadband GaN HEMT power amplifier intended for point-to-point radios, electronic warfare systems, and test and measurement applications. The proposed power amplifier ...
A multioctave 8 GHz-40 GHz receiver for radio astronomy
(IEEE, 2023-04)
Accurate measurement of angular positions on the sky requires a well-defined system of reference, something that in practice is realized by the International Celestial Reference Frame (ICRF) with observations of distant ...
X- To Ka- Band cryogenic LNA module for very long baseline interferometry
(IEEE, 2020)
We report a new result of a packaged low noise amplifier (LNA) module with wide bandwidth of 5 to 35 GHz and low noise temperature performance of 10 -18 K, while operated at 10 K ambient. The LNA used 3-stages of sub-50 ...
