Efficiency linearity trade off is an important criteria in low earth orbit (LEO) satellite transmitter. In this paper, two X-band power amplifiers, one class A power amplifier and one harmonically terminated class A amplifier, are designed with an output power of 7W, total gain of 18.5dB and bandwidth of 200MHz are designed and compared in terms of efficiency and linearity. With acceptable linearity, the former is expected to give 30% efficiency while the later is expected to give 50% efficiency at 8.2GHz with FLM7785-4F and FLM7785-12F internally matched transistors from Fujitsu Quantum Devices. © 2003 by the American Institute of Aeronautics and Astronautics, Inc.

A two stage solid state power amplifier at X-band for satellite communication
Sen, Özlem; Dudak, C.; Nakiboğlu, Barış (2003-01-01)
Low earth orbit (LEO) satellites play an important role in earth observation and communication fields. Since communication with LEO has time limitation, it is important to have high data rate transmitters in addition to having properties as small volume, lightness and efficiency. In this work, an X-band (8.2 GHz) solid state power amplifier is designed with an output power of 7W, total gain of 18.0dB and bandwidth of 200MHz as a part of an onboard transmitter with data rate of 100 Mbps. The power amplifier ...
A Control moment gyroscope based on rotational vibrations, dynamic model and experimentation
Arberkli, Ferhat; Azgın, Kıvanç; Department of Mechanical Engineering (2018)
Satellite attitude determination and control system is one of the main subsystems of a spacecraft. Within this domain, there are several types of actuators; such as reaction wheels, control moment gyroscopes (CMG), propulsion systems and magnetic torque rods. All of them are common and currently being used on modern satellites and space stations depending on the application. Conventional reaction wheel and CMG operation are based on the continuous rotation of their rotor mass to exchange angular momentum be...
X Band TX reject waveguide bandpass filter design for satellite communication systems
Çelebi, İrem; Koç, Seyit Sencer; Department of Electrical and Electronics Engineering (2018)
For several applications such as satellite communication, filters are required since antenna systems are operating as both receiving and transmitting. There is a possibility of leakage from transmit to the receive path in these kind of systems which needs to be isolated in order to protect equipments after filter. Low loss, high isolation and bandpass characteristics are desired for the filtering, which can be validated with waveguide filters. In this study, bandpass waveguide filter design operating in X-Band f...
Link analysis for BILSAT-1
Telli, Ali; Es, Alphan (2006-03-11)
,BILSAT-1, a 130 kg micro satellite, is Turkey's,2 first Low Earth Orbit Earth (LEO) observation satellite(1,2). The project was started in August 2001 at Surrey Satellite Technologies Limited (SSTL)'s facilities in Guildford, UK and BILSAT-1 was launched successfully from Plesetsk Cosmodrome, Russia in 27 September 2003. The main objective of the mission is remote sensing. The communications subsystem is a core system for Earth observation satellite. It is generally used for telemetry/telecommand signaling...
An x-band transmitter for satellite communication
Sen, OA; Sunay, HK; Dudak, C (2003-11-22)
Modern satellite communication systems require high data rate, high-efficiency and simple transmitters, without sacrificing efficiency and linearity depending on the modulation scheme. Main purpose of this study is to design a transmitter with data rates up to 100 Mb/s, BPSK/QPSK/OQPSK modulation and 7W output power at 8.2 GHz for low earth orbit (LEO) satellites in order to satisfy the high data rate demand. Since the transmitter should be a low power, simple and low weight one, the power amplifier will be...
