The front-end consists of a C-band low-noise block down-converter and a L-band receiver. The receiver is designed to meet the requirements about wide-band, high sensitivity, large dynamic range, low noise figure. To reduce noise figure and increase bandwidth, the C-band low-noise amplifier is designed using T-type of matching network with negative feedback and the L-band LNA is designed using cascoded techniques. The local oscillator uses a voltage controlled oscillator combine phase locked loop to reduce the phase noise and select channels. The front-end has successfully been designed and fabricated with parameters: Input frequency is C-band; sensitivity is greater than -130 dBm for C-band receiver and is greater than -110dBm for L-band receiver; output signals are AM/FM demodulation, I/Q demodulation, baseband signals. date: 2016-10 date_type: published id_number: DOI: 10.11591/ijece.v6i5.10480 full_text_status: public publication: International Journal of Electrical and Computer Engineering volume: Vol.6, number: No.5 pagerange: P.2282-P.2290 refereed: FALSE issn: 2088-8708 citation: Tran, Van Hoi and Ngo, Thi Lanh and Nguyen, Xuan Truong and Nguyen, Huu Duc and Bach Gia, Duong (2016) Design of a Front-End for Satellite Receiver.
