Abstract

In this paper we present a sub-harmonically pumped mixer using a mature, commercially available, low cost 0.5 /spl mu/m MESFET process. Housed in a BGA package, the downconverter IC forms an integral part of a receiver system solution in the 17-20 GHz band by supporting an IF of DC to 5 GHz. An on-board LO amplifier is incorporated reducing the drive level requirement to 0 dBm at 8-9 GHz. Due to the use of lumped element matching throughout the design, the mixer itself occupies only 0.2 mm/sup 2/ with an overall chip size of 0.7 mm/sup 2/. The integral LO amplifier is biased at +5 V, drawing 49 mA.

一种用于卫星接收机应用的低成本17- 20ghz次谐波下变频器

在本文中，我们提出了一种亚谐波泵浦混频器，使用成熟的，市售的，低成本的0.5 /spl mu/m MESFET工艺。下变频集成电路采用BGA封装，通过支持直流至5 GHz的中频，构成了17-20 GHz频段接收器系统解决方案的组成部分。集成了板载LO放大器，将驱动电平要求降低到8-9 GHz时的0 dBm。由于在整个设计中使用了集总元件匹配，混合器本身仅占用0.2 mm/sup 2/，整体芯片尺寸为0.7 mm/sup 2/。整体式LO放大器的偏置电压为+5 V，输出功率为49ma。
