GaAs devices and the MIC applications in satellite broadcasting
GaAs devices, such as low-noise high-electron-mobility transistors (HEMT), low-noise FET, and wideband UHF amplifiers. are used extensively for satellite broadcasting receivers, especially in LNBs (low-noise block downconverters). The Ku-band prescaler for nonadjusting local oscillators, the active bandpass filter for miniaturized filters, and the monolithic ICs for high-volume production have been developed recently. A summary of information on GaAs devices and the monolithic microwave ICs (MMICs) is presented. Opinions on the merits and future availability of MMICs and discrete circuits are given. The status of satellite broadcasting in Japan is discussed.<>
