Advanced Optical Developments for inter-Satellite Communication
Lower cost: The cost of disposing FSO is lower than that of an RF with comparable data rate. There are no cables to deploy, no expensive rooftop installations required. Based on a recent finding done by an FSO company based in Canada 'fSONA', the cost per Mbps per month based on FSO is about half that of RF based systems [1]. Huge modulation bandwidth: Generally Optical carrier wavelength which...
متن کاملA CMOS Analog Front-end Receiver with Desensitization to Input Capacitance for Broadband Optical Wireless Communication
Line-of-sight optical wireless channels are emerging as a promising broadband wireless access technology. This paper describes a front-end transimpedance amplifier (TIA) that is designed to overcome challenges faced by high-speed optical wireless links requiring receivers with wide field-of-view (FOV) and high dynamic range for signal acquisition/tracking. This transimpedance amplifier employs ...
متن کاملTuned Optical Receiver Front Ends
Unified analytical expressions have been derived for calculating the resonant frequencies, transimpedances and equivalent input noise current densities of the four most widely used tuned optical receiver front ends built with FET’s and p-i-n diodes. A more accurate FET model has been used to improve the accuracy of the analysis. The Miller’s capacitance has been taken into account, and its impa...
متن کاملChaotic Behavior in Receiver Front-end Limiters
A delay nonlinear differential equation is proposed to investigate the condition of the microwave chaotic behavior existing between the antenna and the front-end protection circuit of a receiver such as the radar front-end limiter circuit. This investigation concerns the case of intentional or unintentional signals applied to the antenna outside of its bandwidth. Bifurcation diagrams show that ...
متن کاملWCDMA Direct Conversion Receiver Front End
This paper presents a 2.14GHz RF front end for Wide-band Code Division Multiple Access (WCDMA) receiver. The receiver is based on direct conversion architecture and implements a low noise amplifier (LNA) and a quadrature mixer in 0.25μm CMOS process. The receiver achieves a noise figure (NF) of 8.93dB, provides a gain of 17.14dB, has an IIP3 of -15.04dB and dissipate 72.15mW at 2.5V.
