%T Research, Design and Fabrication of a Microwave Active Filter for Nanosatellite’s Receiver Front-ends at S-band
%X Small satellites become a future trend in communications satellite. In this field, nanosatellites are a very promising class which have many advantages over larger satellite segments, such as simplicity, lower manufacturing expense and the ease of deploying in constellation at Low Earth Orbit. This paper is targeted at study, design and fabrication of a microwave active filter for the receiver front-ends using coupled line filter structure for nanosatellite missions. The whole active filter system is a combination of a microstrip bandpass filter and a preceding two-stage wideband low noise amplifier using FET devices. The low noise amplifier plays as an active element, which provides gain and compensates noise from the filter. The system operates in the frequency range of 2 - 2.4 GHz and has a peaked gain of around 16 dB at 2.36 GHz, which is suitable for nanosatellite communication’s applications at S-band. The simulated and measured results of this active filter configuration are presented.
