Divider and signal generation system using the same

Abstract

Provided is a divider capable of accurately evaluating an object to be measured without being affected by impedance of a terminal to be measured of the object to be measured, and a signal generation system. There is provided a divider (100) including an input terminal (10), a plurality of output terminals (50-1, 50-2,......50-n), a distribution unit (20) that distributes a high frequency signal input to the input terminal and outputs signals from a plurality of distribution unit outputs (30-1, 30-2,......30-n), and a plurality of reflected wave blocking units (40-1, 40-2,......40-n) that are respectively connected to the plurality of distribution unit outputs and used for blocking reflected waves reflected from the output terminals. Outputs from the plurality of reflected wave blocking units are output from the plurality of output terminals.

Description

technical field [0001] The invention relates to a distributor for processing high-frequency signals. Background technique [0002] A splitter is also called a power splitter, a power divider, a splitter, etc., and is a device that distributes an input high-frequency signal to multiple outputs. For example, high-frequency signals from several MHz to tens of GHz are processed. [0003] As an example of a distributor application, it is used to distribute an input high-frequency signal to a plurality of receiving units in a wireless communication device. In the field of measurement, for example, the output signal of the signal generator is input to the distributor, and the high-frequency signal is distributed, so that the signals distributed to a plurality of measured objects are respectively sent. For example, the following patent documents are known figure 1 The allocators exposed in . And, the structure example of the existing allocator is shown in Figure 12 . [0004]...

AI Technical Summary

Problems solved by technology

[0006] However, in the simultaneous measurement of a plurality of measurement terminals distributed by the existing distributor, the impedance of other measurement terminals or signal input terminals occurs due to impedance mismatch due to poor contact of the measurement terminal connected to the object to be measured. As a result, the signal level of a plurality of distributed measurement signals differs, for example, a difference of 1 dB or more, and there is a problem that accurate simultaneous measurement cannot be performed.
