描述

在工作中,我們會遇到一些關於GPS研究方面的使用者,他們往往要求使用一個GPS信號源,來為多台GPS接收機提供GPS信號,為了適應這種一源多機(一個GPS信號源供多台機器使用)的GPS工作模式,就必須使用功率分配器(功分器),下面是有關功分器的一些知識:

 功分器是一種將一路輸入信號能量分成兩路或多路輸出相等或不相等能量的器件,也可反過來將多路信號能量合成一路輸出,此時也可稱為合路器,一個功分器的輸出埠之間應保證一定的隔離度。

 功分器通常備為能量的等值分配,通過阻抗變換線的級聯與隔離電阻的選擇,具有很寬的頻帶特性。

 有源功分器:其供電取自衛星接收機向天線高頻頭的供電,有源功分器多見於六功分,八功分和少數四功分.主要原理是增加了兩隻低噪寬頻三級管組成的兩級放大單元.

 無源功分器:通過電感、電阻和電容進行無源分配的。常見的無源功分器有二功分、四功分等。

In our work, we will meet some users about GPS research. They often require the use of a GPS signal source to provide GPS signals for multiple GPS receivers. In order to adapt to this one source, multiple devices (a GPS signal source) For the GPS working mode of multiple machines, a power divider (power divider) must be used. Here are some knowledge about power dividers:

 A power divider is a device that divides the energy of an input signal into two or more channels with equal or unequal energy. It can also combine the energy of multiple signals into one output. At this time, it can also be called a combiner. A certain degree of isolation should be guaranteed between the output ports of the splitter.

 The power divider is usually prepared for the equal distribution of energy, through the cascade of impedance conversion lines and the selection of isolation resistance; it has a wide frequency band characteristic.

Active power divider: its power supply is taken from the power supply of the satellite receiver to the antenna tuner. Active power dividers are mostly found in six power points, eight power points and a few four power points. The main principle is to add two low A two-stage amplifying unit composed of a noise broadband three-stage tube. 

Passive power divider: Passive distribution through inductance, resistance and capacitance. Common passive power dividers include two power points, four power points, and so on.
