Abstract
A compact low-noise-block (LNB) downconverter module for use in direct broadcast satellite (DBS) reception utilizing only GaAs monolithic microwave integrated circuits (MMICs) has been successfully demonstrated. Four kinds of MMICs designed with 0.5- mu m-gate pulse-doped MESFETs were assembled in a miniaturized flat package (24.5 mm*17.8 mm*6.0 mm). 52-dB conversion gain and a 2.1-dB noise figure were obtained using no discrete high-electron-mobility transistors (HEMTs) in the preceding stage and no stub-tuning.<>
