说到射频的难点不得不提杂散,杂散也是射频被称为“玄学”的来源。杂散也是学习射频必经的一个难点。 No.1 杂散是什么? 杂散(Spurious Emissions),指的是必要带宽之外的一个或多个频率上的发射,其发射电平可以降低而不致影响相应信息的传递。杂散发射包含谐波发射、寄生发...
“Spurious emissions”是指无线电发射设备发射出来的无意识信号,它们可能会干扰其他无线电发射设备的正常运行。它们通常是在指定的频率范围之外的频率发射出来的。 在通信中,“spurious emissions”是一种不可控的噪声,它可以影响正常的通信信号,从而影响通信的质量。它可能会影响信号的传输质量,降低信号的接收质量,并可能...

After a thorough investigation, the team initiated a RAMEC to filter the chip detector from spurious emissions from other sources that cause a false signal through EMI. Chasing ghosts To gain licenses in the United States and some other countries, Iridium pledged that for a few hours each day,...

杂散辐射Spurious Emissions,以及Out band of emission 下载积分: 1588 内容提示: 杂散辐射是指例如谐波,寄生发射,互调产物以及变频产物(例如本振泄漏)等非理想的无用的发射机产物。 对于它的考核,不应该只针对 PA,其实它是对基站或者直放站整体的一个限制,PA 除了要做得尽量的线性以外,有些是它无能为力的,还...
