This paper presents the measurement and analysis method for detection of the mm-wave signal at 96 GHz, by using a low-cost microbolometer infrared (IR) camera with 70 mu m pixel-pitch optimized for detection in the 8-12 mu m (LWIR) range. The mm-wave beam derived from a multiplied Schottky diode based source is detected within similar to 65 % of the whole area of a 160x120 pixel focal plane array microbolometer sensor. Under similar to 73 mW incident power, responsivity is measured as 7.3 V/W, and the average noise for the measurement is determined as 12 mu V, which includes both detector and readout electronics contribution. From the measured parameters, the integrated Noise Equivalent Power (NEP) is calculated as 1.63 mu W within the 7.8 kHz readout bandwidth. By using a simple setup, it is shown that a low-cost microbolometer camera which is designed for LWIR range can detect a distinct mm-wave beam at 96 GHz.

Assessment of large format InP/InGaAs quantum well infrared photodetector focal plane array
Ozer, S; Cellek, OO; Beşikci, Cengiz (Elsevier BV, 2005-10-01)
We report the fabrication and characteristics of large format (640 x 512) InP/In0.53Ga0.47As long wavelength infrared (LWIR) quantum well infrared photodetector (QWIP) focal plane array (FPA). The FPA, which is hybridized to a read-out integrated circuit having a charge capacity of 1.1 x 10(7) electrons, yielded a mean noise equivalent temperature difference (NETD) of similar to 40 mK at a cold finger temperature as high as 77 K. The performance of the FPA, being comparable to that of AlGaAs/GaAs QWIP FPAs,...
Detection of high order M-ARY QAM symbols under transmitter nonlinearities
Gülgün, Ziya; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2018)
We will investigate the nonlinear effects of power amplifiers on large constellation Quadrature Amplitude Modulation (QAM) in this study. A more than potential feat to enhance transmission rates in next generation wireless networks is high order QAM along with mm-wave transmission. Meanwhile, different types of nonlinearities in the transmitter side may hamper the transmitter rate and decrease receiver performances. From literature, outermost constellation points of QAM schemes are usually more adversely af...
Resolving the radio nebula around beta Lyrae
UMANA, G; MAXTED, P F L; TRIGILIO, CORRADO; FENDER, R P; LEONE, FRANCESCO; Yerli, Sinan Kaan (2000-06-01)
In this paper we present high spatial resolution radio images of the puzzling binary system beta Lyrae obtained with MERLIN at 5 GHz. We find a nebula surrounding the binary with a brightness temperature of (11000 +/- 700)K approximately 40 AU across. This definitively confirms the thermal origin of the radio emission, which is consistent with emission from the wind of the B6-8II component (mass loss of order of 10(-7) M.yr(-1)), ionized by the radiation field of the hotter companion. This nebula, surroundi...
An uncooled microbolometer infrared focal plane array in standard CMOS
Tezcan, Ds; Eminoglu, S; Akar, Os; Akın, Tayfun (2001-01-24)
This paper reports implementation of a low-cost microbolometer focal plane array using n-well layer in a CMOS process as the microbolometer material. N-well microbolometer structures are suspended for thermal isolation by postetching of fabricated CMOS dies using silicon bulk-micromachining techniques. Although n-well has a moderate TCR of 0.5-0.65 %/K at 300 K, it still provides a reasonable performance due to its single crystal structure which contributes low 1/f noise. Detailed thermal simulations in ANS...
Measurement of the charge asymmetry in top quark pair production in pp collisions at root s=7 TeV using the ATLAS detector
Aad, G.; et. al. (2012-06-01)
A measurement of the top-antitop production charge asymmetry A(C) is presented using data corresponding to an integrated luminosity of 1.04 fb(-1) of pp collisions at root s = 7 TeV collected by the ATLAS detector at the LHC. Events are selected with a single lepton (electron or muon), missing transverse momentum and at least four jets of which at least one jet is identified as coming from a b-quark. A kinematic fit is used to reconstruct the t (t) over bar event topology. After background subtraction, a Ba...
