DBS 수신기를 위한 Ku 대역 Dual-Gate Mixer의 설계
백정기 忠南大學校 産業技術硏究所 1995 산업기술연구논문집 Vol.10 No.1
A Ku-band monolithic dual-gate mixer with 0.25umx200um HEMT is designed. Simulation results reveal that 3.88dB conversion gain, 8.38dB noise figure, -13.25dB RF return loss and -15.09dB LO return loss can be obtained for 11.7GHz-12.2GHz RF frequency and 10.75GHz Lo frequency. Variation test show that the yield of 62.5% can be achieved for 10 variation of R, C, gate width and 5% variation of L. HEMT large-signal model parameters used for simulation are based on the data from the ETRI foundry.
