C-Band Satellite Communications
30th AIAA International Communications Satellite System Conference (ICSSC), 2012Commercial satellite communications began in the early 1960s, building on C-band technologies developed in previous decades for point-to-point terrestrial microwave links. As the industry has grown, C-band usage in satellite communications has been augmented, but not replaced, by the usage of higher frequency bands.

INHERITANCE OF Q AND C BAND POLYMORPHISMS
Canadian Journal of Genetics and Cytology, 1977Sequential Q and C banding of chromosomes from 36 individuals in three unrelated families revealed Q band variants on 6 different chromosomes and C band variants on 14 different chromosomes. These variants were inherited in Mendelian fashion with one exception in which a C band variant absent in the parents was found in a child. Although some of the Q

C-Band Heteromorphism in Breast Cancer Patients
Cancer Genetics and Cytogenetics, 1985The pattern of heteromorphism in the C-band-positive constitutive heterochromatin of human chromosomes #1, #9, and #16 was studied in peripheral lymphocytes of 54 breast cancer patients and 78 control individuals. The parameters of the heterochromatic regions analyzed were relative size, symmetry-asymmetry within homologous pairs, and prevalence of ...

Using Leishmans stain for C-banding, the authors indicate the use of this approach for identifying chromosome aberrations and clarifying taxonomic relationships and seek to apply them to resolve the origin and evolutionary history of V. faba. Chromosomes of six species of Vicia were examined including four accessions of V. faba.

The ultrastructure of G- and C-banded chromosomes
Experimental Cell Research, 1975Abstract A method of visualizing chromosome bands by electron microscopy has been used to investigate the fine structural organization of G- and C-banded chromosomes. The following information has been obtained: 1. 1. G-bands, produced by trypsinization, were electron dense regions of highly packed chromatin fibres separated by regions in which ...

Telecommunications Policy, 1988
Abstract This paper examines the new form of C-band direct and investigates the problems surrounding it, specifically the issue of scrambling, and the actions taken by Congress and the FCC. It begins with a discussion of the emergence of C-band direct and then gives the different views on scrambling.

A Design Study of a C-Band Crestatron [PDF]
, 2007 Abstract : This memorandum presents a design study of a high power C-band Crestatron Amplifier. While conventional helix traveling-wave tubes (TWT's) are operated in an exponentially growing-wave mode, the Crestatron operates a "beating-wave" regime where three constant-amplitude voltage waves traveling at different phase velocities along the helix ...

14th International Conference on Microwaves, Radar and Wireless Communications. MIKON - 2002. Conference Proceedings (IEEE Cat.No.02EX562), 2003
3D pulse-coherent radar with electronic beam scanning working in the C band will be the main source of information for a ship's defence systems. A functional model of this radar system has been built. The system enables automatic detection and tracking of over 100 maritime and air targets.

Design of LNA for C band applications
2017 IEEE International Conference on Circuits and Systems (ICCS), 2017Amplification is one of the most vital operation in modern RF and microwave communication systems. Earlier microwave amplifiers were made of tubes like klystron, TWT's etc. but due to the development of solid state device technology now-a-days the microwave amplifiers are often designed using these devices like BJT's, FET's and newly developed ...
