摘要

一种紧凑的低噪声块(LNB)下变频模块用于直接广播卫星(DBS)接收，仅使用砷化镓单片微波集成电路(mmic)已经成功演示。采用0.5 μ m栅极脉冲掺杂mesfet设计了四种mmic，并将其组装在小型化的平面封装(24.5 mm*17.8 mm*6.0 mm)中。在前一阶段没有使用离散高电子迁移率晶体管(hemt)，也没有进行短段调谐的情况下，获得了52 db的转换增益和2.1 db的噪声系数。

Ultra small sized low noise block downconverter module

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.<>
