Abstract

An 8-bit 360o sawtooth modulated phase shifter is used to apply very small frequency offsets to RF signals between 7 and 8 GHz. Offsets between 6 Hz and 10MHz can be obtained. Such frequency offsets can be used to generate orthogonal signals, which are required in e.g. MIMO applications. Each undesired frequency component is suppressed to below -30 dBc. The phase modulator is realized in a 250 nm SiGe BICMOS technology.

一种用于MIMO信号产生的7-8 GHz Serrodyne调制器

一个8位360锯齿调制移相器用于对7到8 GHz之间的射频信号施加非常小的频率偏移。可获得6hz ~ 10MHz的偏移量。这种频率偏移可以用来产生正交信号，这在例如MIMO应用中是必需的。每个不需要的频率分量被抑制到-30 dBc以下。相位调制器采用250nm SiGe BICMOS技术实现。
